The dream of making quantum memristors is becoming a reality. Machine learning suggests an ideal structure for a quantum memristor that may one day outperform current computing systems.

The dream of making quantum memristors is becoming a reality

Scientists are increasingly turning to the unique properties of quantum mechanics to create technologies with unprecedented levels of performance, security, and energy efficiency.

According to Advanced Science News, the latest examples in this field of discovery are quantum memristors, which, if implemented in real-world systems, promise to consume much less energy than conventional computer memories.

Carlos Hernani-Morales, a researcher at the University of Valencia in Spain, said: Quantum memristors are devices designed to mimic the properties of classical memristors but include quantum twists.

Morales continued: Memristors are the fourth element of the basic circuit, along with resistance, inductor, and capacitor, which were proposed by “Leon Chua” (Leon Chua), an electrical and computer engineer, in 1971, and the “HP Labs” research group named them It was implemented on a trial basis in 2008. Memristors have a variable resistance that depends on the current or voltage applied to them and the ability to maintain the last resistance value. Therefore, they act as a memory device.

One area where quantum memristors can excel is in neuromorphic computing. The goal of neuromorphic computing is to create devices that function similarly to the human brain.

Morales explained: Neural computing is a brain-inspired approach to computing and is one of the areas that could benefit from advances in quantum memristor technology because these systems rely on memristors’ ability to store information without the need for a constant power supply, and the properties of neurons. They show the human brain.

Despite the potential of quantum memristors, scientists have yet to develop a practical device. Although quantum memristors are promising, as with many technologies related to quantum computing, there is currently no obvious advantage to using them over a classical example, Morales said.

Implementation of quantum memristors has been challenging until now due to several complicating factors. Quantum systems are highly sensitive to environmental noise and this makes them unstable. This makes it difficult to maintain quantum coherence, which allows particles such as electrons or photons to exist simultaneously in multiple states and maintain a fixed relationship between these states.

In addition, precise control of quantum states such as superposition and entanglement requires complex equipment and methods, and finding suitable materials that support quantum properties and exhibit memristor behavior has been challenging.

Machine learning

Rather than the usual trial-and-error approach, Morales and his team sought to use machine learning to provide a glimpse of what might be possible. We studied the use of machine learning models to find an optimal set of parameters that maximizes the memory capacity in a single quantum memristor and a system consisting of two quantum memristors, they wrote in their paper.

In particular, the research group investigated a type of quantum memristor, which consists of conventional electronic components combined with a superconducting current loop, and uses the effects of quantum mechanics to store and process information in ways that classical memristors cannot. Do.

By adjusting different parameters of the memristor, including the magnetic field affecting the current loop, the machine learning algorithm identified the optimal structure of the memristor, which almost reached the maximum capacity of the memory theory.

Also, the researchers investigated the simplest systems, which consisted of only two interwoven memristors. The entanglement of memristors represents a quantum phenomenon in which the states of several memristors are interconnected in such a way that the state of one memristor cannot be described independently of another state. This helps improve memristor properties such as efficient information processing.

“We find that, in the optimal case, there is strong evidence supporting a link between quantum coherence and memristor behavior,” the researchers wrote, adding to existing knowledge or further confirming theoretical predictions.

It will also help identify future quantum memory devices, bringing scientists one step closer to viable and useful neuromorphic quantum computing.

Although these findings provide important information about the ideal structure of an active quantum memristor capable of outperforming current computing systems, further investigation is needed before practical implementation.

Additionally, the research group only focused on a system consisting of two quantum memristors, leaving unanswered questions about the feasibility and potential benefits of entangling larger numbers.

The theoretical analysis did not reveal any method to keep memristors in an entangled state, ignoring an important challenge in quantum computing that maintaining qubit entanglement can be transient due to environmental effects. The challenge is that current qubits can only be effectively stored in an entanglement for a fraction of a second.

Addressing these challenges will not be easy, but researchers can pave the way for the development of highly efficient and robust quantum computing systems that take advantage of the unique capabilities of entangled memristors.

This research was published in “Advanced Quantum Technologies” magazine.

Kali Linux
Kali Linux is a special distribution primarily used for penetration testing and security research and provides a set of tools for white hat hackers.

What is Kali Linux? Everything you need to know about this popular but mysterious distribution

In today’s technology era, as devices and tools become more advanced, their negative and destructive side also become more complex, and as a result, interaction with them requires more care. Currently, with the pervasiveness of the Internet the strong dependence of our daily lives on it, and the emergence of artificial intelligence, cyber threats have also increasingly spread, and the news of hacking various platforms is heard from left and right.

Considering the cyberization of part of people’s lives (entertainment, chat, and earning), the importance of strong cyber security measures cannot be ignored. Kali Linux or in English Kali Linux is a powerful and open-source Linux distribution that is specifically used for penetration testing and digital research and is considered one of the most important tools in the field of cyber security.

Kali Linux desktop home pageKali Linux 2024.3

Every techie has probably thought of installing Kali Linux, even via a virtual machine, to poke around and entertain their inner little scientist.

When users first encounter Kali tools, they see strange names such as BeFF Bettercap Hashcat Metasploit, or Nmap, which are almost difficult to guess their use from the name. Overall, Kali is a powerful distribution, and working with it requires a deep understanding of its tools.

What is Kali Linux?

Kali Linux, formerly known as BackTrack Linux, is a Debian-based Linux distribution developed by Offsec. This Linux distribution hosts hundreds of different tools used for penetration testing, reverse engineering, and vulnerability detection of networks and websites.

Kali Linux user environment

Due to the fact that Kali is developed based on Debian, it has high stability and security, and its Debian base allows it to benefit from vast software repositories and a similar package management system. In addition, if you are in the category of users who are already familiar with Debian Linux distributions such as Ubuntu, navigating Kali will not be difficult for you; But for users of other operating systems to enter the world of Linux, learning Kali takes more time.

Another important goal of Kali developers is to give the user unlimited freedom to have an open-source and ever-evolving platform and not just be limited to the tools available on the platform. Thus, even the most detailed parts of the software on Kali are open to optimization by the user.

Who uses Kali?

If you are imagining a sequence of Mr. You’re Robot, which depicts a hall full of professional hackers, and the hackers are sitting behind their systems in hoodies, you’re completely wrong. The use of Kali Linux does not require special clothing and there are professional and skilled experts who appear in their company and workplace every day and are responsible for simulating attacks on the network and discovering and fixing its vulnerabilities.

Other people for whom the use of Kali Linux is useful are instructors who plan to train the next generation of white hat hackers and ethical hackers, and Kali Linux is considered the best toolbox for training.

Key features of Kali Linux

Kali Linux has a variety of tools in various categories, including intelligence gathering tools, vulnerability analysis tools, wireless attacks, password mining, and social engineering tools. Do not forget that one of the main foundations of hacking and penetration is social engineering.

In Kali Linux, you can use Nmap to scan a network and identify its open ports, Metasploit tool is also provided to exploit a vulnerability, and Wireshark should be used to go deep into the traffic of a network.

Tools like Wifite and Airgeddon are also pre-installed on the Kali platform to check the security of your Wi-Fi network. In fact, Wifite automates the process of cracking WiFi passwords, while Airgeddon provides a convenient environment for assessing wireless network security.

Regardless of the tools and programs that are available by default on the platform immediately after installation, users can install other programs they need by connecting to the Internet by learning how to install the program on Linux.

Metasploit tool on Kali LinuxMetasploit tool on Kali Linux

The Kali developers have paid attention to every detail and even included a custom kernel kernel for packet injection, which plays a key role when working with Wi-Fi. In addition, all packages are signed with GNU Privacy Guard to assure the user about the security of the platform.

Features of Kali based on the introduction on the official website:

  • It is free and will always be free.
  • Git is open source.
  • It conforms to the Filesystem Hierarchy Standard.
  • It is compatible with a wide range of devices.
  • It is developed in a safe environment.
  • Supports multiple languages; Of course, the platform tools are in English.
  • Compatible with ARMEL and ARMHF.

Why is Kali Linux not suitable for everyone?

Kali tools are very powerful and require the same amount of knowledge and experience to use them properly. For example, a normal user might want to scan his home Wi-Fi network and find possible vulnerabilities by installing Kali. But in this process, with Kali’s tools, he creates a problem that has serious consequences for him.

Installing the program through the terminal in Kali LinuxInstalling the program in Kali Linux through the terminal

Suppose you try to execute a script without sufficient knowledge and because Kali is connected to the Internet, this script affects the computer of a certain person or organization. Do not forget that Kali is not designed and optimized for the everyday use of ordinary people and common tasks such as web browsing, editing documents and watching movies.

Go to Ubuntu to satisfy your curiosity and experience the Linux environment

If you are just curious about working with Linux and getting to know the environment of Linux distributions, better options can be found compared to Kali. Usually, the most recommended migration from other platforms to Linux ends up with the Ubuntu distribution, which has a user-friendly interface and a huge support community and runs everyday processes like any other operating system.

Linux Mint is another option recommended for beginners, especially for users who are used to traditional desktops. On the other hand, Windows users usually associate more with Zorin OS. These distributions are all developed for everyday use and perform tasks such as web browsing, editing documents and even running games very well.

Getting started with Kali

Finally, if you decide to install Kali Linux, you should download it from the official Kali website. On the Kali website, you can see different versions of Kali for installation in different ways, and according to your conditions and desired installation method, you can download the desired version.

To install Linux distributions, it should be noted that it is possible to install Linux on Flash or that the user can install the desired distribution on the virtual machine. Installing Kali on a virtual machine has the advantage that all events are kept in isolation and no damage is done to the user’s main operating system.

The Kali Linux distribution is considered the most popular platform for hackers and is designed for specific purposes where everyday use is not among its goals; Therefore, it is not necessary to install it for specialized work and of course to meet the needs of curiosity, but for normal use it is recommended to go for other distributions of Linux.

Dear Zomit users, what is your opinion about the user experience with Kali Linux? Do you recommend installing it?

Sony Brand Story; From the production of rice cookers to becoming one of the most famous companies in the world

Published

Sony
Sony has released many innovative products to the market and today it is considered one of the most well-known companies in the world.

Sony brand story; From the production of rice cookers to becoming one of the most famous companies in the world

Sony is a Japanese multinational company headquartered in Minato, Tokyo. This company provides electrical services, gaming, entertainment, and financial services.

Sony is known as one of the pioneers in the production of electrical products and in recent years it has improved its position among the top companies in the world. Sony consists of many subsidiaries, the most famous of which are Sony Pictures, Sony Music, Sony Mobile, Sony Entertainment, and Financial Holding.

The story of the formation of the Sony brand

Masaru Ibuka returned to Tokyo from World War II in September 1945 to start a new job in the Japanese capital. He set up his workshop in an old, war-torn building with only eight employees. Their initial office walls were full of cracks and had no windows, but over time as their business progressed, the office building also improved.

In October of that year, Ibuka and his group launched a new company called Tokyo Tsushin Kogi, or Tokyo Institute of Communications Research. At that time, everyone was eager to work in the new company and wanted to use their engineering knowledge to rebuild Japan. However, no one knew where to start. Most of the employees were paid from Ibuka’s small savings and they had to work hard to survive.

The story of the formation of Sony goes back to 1945; When Masaru Ibuka returned from World War II

At that time and during the Second World War, people were thirsty to hear the news of the day. As a result, they came up with an interesting idea that changed the fate of the company forever. Most of the radios at that time were either destroyed by the war or could not receive radio waves due to police interference.

The Ibuka company repaired broken radios and also made it possible to receive waves using a series of converters. It didn’t take long for this model of radio to gain many fans among people.

Their business was in the center of attention and for this reason one of the Japanese newspapers published an article about them. This article not only got them more customers but also brought Ibuka’s old friend, Akio Morita, closer to him.

Sony
Ibuka and Morita, the founders of Sony Corporation, first met on a research committee studying new types of war weapons.

After some time passed, despite the big age difference, a deep friendship between Ibuka and Morita was formed. After the end of the war, Morita returned to his hometown and the communication between them was cut off. Until one day he read his friend’s name in a newspaper article and called Ibuka. Ibuka also asked him to get to Tokyo as soon as possible to start working with him again.

Sony’s brand name was originally supposed to be TTK or Totsuko

They were looking for a new name to advertise their company globally. Their intention was to choose the abbreviation of the company’s name, TTK, for advertising, but this name was already used. The word Totsuko was also another suggested name. But during his trip to America, Morita realized that it is difficult for Americans to pronounce this name.

They finally chose the name Sony from the combination of 2 words Sonus meaning sound and Sonny meaning young boy. Their purpose in choosing this name was to pronounce it in the same way in all languages ​​of the world.

The company’s first product was a rice cooker, which, contrary to expectations, failed to meet expectations and failed. They did not get discouraged after their first failure and devoted more money to research. They focused on developing products that would benefit the Japanese people.

Sony; The first brand

During 77 years of operation, Sony has been able to launch the first product in many markets of the world. From Japan’s first tape recorder to Japan’s first transistor radio and other products.

Tape recorder

Sony

In 1950, the first Japanese tape recorder was made from its American model. This device was also not well received until Sony released a translated version of 999 Ways to Use the tape recorder.

After people became familiar with the product’s uses, the purchase request increased and the Sony tape recorder sold well. The demand for this product increased so much that the company had to expand its facilities to produce orders.

Transistor radio

Japan’s first transistor radio was introduced in 1955 by Sony.

Portable TV

Sony

In 1960, Sony released the world’s first portable transistor TV. Sony used radio technology to produce this device.

The televisions of that time were big and in every house, a specific room was reserved for them. But these products brought a new definition of personal televisions to the market.

Video tape player

Sony

In 1971, Sony unveiled another product. This player was able to show videotapes in color inside the TV.

Masaru Ibuka retired in 1976 and was succeeded by Akio Morita as CEO.

The first generation Walkman

Sony

In 1979, Sony launched the first generation of Walkmans. These devices were portable and customers could listen to their favorite cassettes anywhere.

Many employees of the company believed that this device could not become popular among people without the ability to record sound. But contrary to their belief, this device introduced a new and successful lifestyle among people and achieved remarkable success.

The first CD player

Sony

The world’s first CD player was launched in 1982 by Sony.

One of Sony’s senior managers, Norio Oga, was elected as the company’s CEO in 1989. Sony bought Columbia Pictures in the same year. This action was considered the biggest purchase of a Japanese company at that time.

PlayStation

Sony

PlayStation is another important product of Sony. This product was sold in the Japanese market in 1994 and entered America and Europe in 1995.

PlayStation became so popular among people that its sales reached 10 million units by the end of 1996, and in 1998, about 50 million of this console had been sold. The production of new models of this product continues and today PlayStation 5 is considered the newest Sony console.

Digital camera

Sony

The first digital camera was launched by Sony in 1995. This device was very well built and recorded high-quality videos.

Sony Mobile

Design of Xperia One Mark 4

Sony Mobile Company started working in 2001 in cooperation with Ericsson. The company’s products were first marketed under the name of Sony Ericsson until Sony bought Ericsson’s shares in 2012. Since then, the phones of this company have entered the market under the name of Sony.

In 2012, Sony was able to win the title of the fourth mobile phone manufacturer. Xperia series mobile phones are the current flagships of this company. The Xperia brand doesn’t sell much at the moment, but Sony continues to produce products.

Vaio laptop

The first generation of Vaio laptops was launched in 1997. These laptops had a slim body and introduced a new concept of personal computers to the world.

Personal life of Masaru Ibuka

Masaru-Ibuka

Masaru Ibuka was born on April 11, 1908 in Nikko, Japan. He graduated from the university in 1933 and worked in a film production company. Ibuka joined the Navy during World War II and was a member of the investigative committee; But after some time in 1945, he left the war to start his own radio repair workshop in Tokyo.

At that time, people followed the news of the world through the radio. As a result, starting a radio-related business was a good idea for a company. Ibuka and Akio founded Sony in 1946. Ibuka used transistors to make his company’s products. Therefore, Sony was introduced to the world as one of the first companies to use this technology for non-combat purposes.

Ibuka was a member of the Navy during World War II

In 1976, Ibuka was awarded an honorary doctorate from the University of Tokyo. He received two other honorary doctorate degrees in 1979 and 1994 from Tokyo and American universities.

Ibuka published a book titled “Kindergarten is Too Late” in 1971. In this book, he claimed that the most important time for human learning is from birth to three years old. As a result, he has suggested ways to teach skills to children at this time.

Ibuka was the leader of Sony until 1976 and then he retired; But even after that, he had a close relationship with company managers and guided them. He died in 1997 at the age of 89 due to heart failure.

Personal life of Akio Morita

Akio-Morita

Akio Morita was born on January 26, 1921 in Japan. He was the eldest of his four siblings. As a result, his father trained him to manage the family business.

Akio was very interested in mathematics and physics and graduated from university with a degree in physics. During World War II, he became a member of the Japanese Army’s Research Committee, and while serving, met his future business partner, Masaru Ibuka.

Morita was a huge fan of all Sony products and worked hard to promote them. For example, the size of their first production radios was slightly larger than the standard shirt pocket size. Because they wanted to market their products as pocket radios, Morita made shirts for their employees with larger pockets to show customers that these radios were pocket radios.

Sony established its first branch in America in 1960. Sony was the first Japanese company to enter the US stock market. In 1994, Morita suffered a stroke while playing tennis and resigned from the chairmanship of Sony. He finally died of pneumonia in 1999 at the age of 78.

Sony failures

Since its establishment in 1964, Sony has produced successful and innovative products. Many of these products were entering the market for the first time, and as a result, they introduced a new concept of technology to the world; But no success story is without failures.

Sony Aibo

Front view of Sony Aibo robotic dog

Sony robots were launched in 1999. These robots were in the form of cute dogs and had the power to learn. These robots could show emotions such as happiness, sadness, anger, surprise, fear and disinterest.

Sony robots were sold at a price of $2,500 and were very popular among their owners. But its high price prevented it from increasing its popularity and eventually, Sony stopped production.

Vaio music device

Sony Vaio music player

In 1979, Sony introduced a new concept of portability to the market by presenting its Walkman. The company had been Apple’s fierce competitor in digital music for two years, but its first product did not perform well.

The biggest mistake of the company was the dependence of files on the ATRACT format. Files with this format could only be used in Sony minidiscs. The ability to share files was the first word in digital music in 2000, and all files were released in MP3 format. As a result, this issue became a big challenge for Sony.

Sony e-Villa

Sony E-Villa with keyboard

In 2001, many companies were offering Internet home appliances, including dedicated terminals for accessing the Internet and web browsers. Sony e-Villa was also a product that was launched with the same purpose.

The e-villa had a 15-inch monitor and a 56 kbps dial-up modem. e-Villa was designed to have access to email services and websites. At that time, there was a lot of competition between these devices and people preferred to use devices with Windows XP. As a result, Sony stopped the production of these products after three months.

Sony Airboard

Sony Airboard from the front

10 years before people became interested in watching videos on tablets, Sony launched a device called Airboard. The tablets of this family were 10 inches and had the possibility to connect to Wi-Fi and broadcast TV channels.

Using the picture-in-picture feature, users could search the Internet and watch TV. This device never caught on because people thought it was just a portable and expensive TV. Therefore, its production was stopped before entering the American market.

Sony PSX

Sony PSX console

In 2003, Sony combined its two products, the PlayStation 2 and the video recorder, and marketed it as a single product. Using this product, customers could record the TV show on the storage memory or DVD at the same time as the game experience.

But the PSX, which was released only in Japan, was much larger and heavier than the PlayStation. Although this product did not have a high price, it could never attract many customers.

The current state of the Sony brand

Sony

Sony is one of the largest Japanese companies by revenue. The company reached the peak of profitability in the 1990s and 2000s due to the launch of its PlayStations, but faced financial problems in the late 2000s.

The global financial crisis, increased competition with PlayStation, and the earthquake in Japan in 2011 went hand in hand with Sony experiencing major failures for three years.

Due to the negative effects caused by natural disasters and exchange rates, the Times magazine called Sony a lack of flexibility and inability to measure the economy, but Sony was able to overcome all the crises in all these years by using innovation and became one of the top companies in the world. become in the television industry.

Sony’s current slogan is Be Moved, and the company aims to emotionally excite its customers with every product it offers.

Sony was able to pocket an operating profit of 1.21 trillion yen (about 8.9 billion dollars) in fiscal year 2022, which is a new record. Sony’s revenue in the final quarter of last year grew by 35 percent to about 3.06 trillion yen ($22.5 billion).

How did the people of the past imagine the future?
We are living a dream that our ancestors did not even dream of. How did the most imaginative people of the last century imagine the future?

How did the people of the past imagine the future?

How can you explain to people in the 1900s that a robot can sweep floors and carpets without any intervention by drawing a map of your house without sounding crazy?

To people of the last century, our technology today seems like magic; But that doesn’t mean they didn’t fantasize about what the future would be like. Many inventors and artists have depicted their own predictions of future technology. Let’s look at these paintings and then comment on their scope.

The future from the perspective of the pastBird postman – 1892

The potential of human flight was one of the concerns of futurists. It is true that aviation has revolutionized our world, but the type of flying equipment and “flying cars” that captured the imagination a century ago will remain for the future.

One of the important innovations that the minds of the ancients often did not imagine is the Internet and modern wireless communications. In today’s world, the flying postman pictured here would probably be out of a job thanks to plain old email.

The future from the perspective of the pastElectric floor washer (electric scrubber) – 1899 | The vacuum cleaner was invented just two years after this image was made.

The idea of ​​a robot vacuum cleaner, now a reality in millions of homes, was apparently beyond imagination in the late 19th century.

The future from the perspective of the pastMachine learning-1901

According to this prediction, teaching was supposed to become a very easy job by the year 2000. The principal simply feeds the history books into the machine, while an assistant (or perhaps a student being punished?) turns the handle and somehow wires the contents of the books to the headsets the students are wearing, and from there into their minds. sends Do you understand the necessity of the presence of the school principal in this process?

The future from the perspective of the pastPhone with photo – 1918

The arrival of video-calling technology was predicted more than a century ago. The Electrical Experimenter magazine wrote in 1918: “Many inventors have attempted to invent a device or machine by which one person can see another while talking on the telephone.” According to the author of the magazine, such a device, which should naturally be called a “telephot”, will be invented sooner or later, because “everyone would like to have such a device.”

Death by video callVideo call – 1942

Another article in the magazine Practical Electrics in 1942 predicted a similar device with moving pictures so interesting it is admirable.

The future from the perspective of the pastwheel of destruction

During World War I, specialized technology magazines were full of ideas that were hoped to bring an end to the long conflict. One of these inventions was the gyro-electric destroyer. “This 45-foot monster is steered by a large gyroscope wheel,” Electrical Experimenter magazine reported. “The destroyer travels at a speed of 40 to 60 miles per hour and because of its large diameter it easily rolls over trenches and other obstacles.”

The future from the perspective of the past
Man’s Best (Electric) Friend – 1923

The vision envisions a robot dog that readers can build for themselves; A wheeled device that operates with batteries and follows its owner’s metal cane through a magnet. It may have a cute face but don’t expect this dog to roll over, play, or react if something bad happens to you.

The idea of ​​artificial pets doesn’t seem so strange nowadays. This is a concept that exists mostly in the field of cyberspace, exemplified by digital home assistants and artificial intelligence-based video game characters.

The future from the perspective of the pastClimate control – 1954

The dramatic image above shows how future humans will be able to control the weather. This article describes an airplane that is dispatched to disperse a cloud that threatens to form a tornado. “In the age of the hydrogen bomb and supersonic flight, it’s possible that science will find ways not only to destroy tornadoes and hurricanes but also to influence weather conditions in ways that will boggle the imagination,” the magazine reports.

In 1967, Philco-Ford, a maker of electrical goods, produced a short film called 1999AD, showing how its future products might transform ordinary homes. The family in the film owns a space-age car, a large wall-filling television, and a large home computer that helps the family (specifically the mother) plan their meals. In the film, we see the father of the family using the computer to check the invoice for the clothes he bought online.
