A group of scientists in China announced that they have achieved a new achievement in the field of (quantum computing), as the Chinese quantum computer (Jiuzhang) succeeded in performing common artificial intelligence tasks 180 times faster. Millions of times faster than the world's most powerful supercomputer.
In this regard, the researchers said: "This new achievement enables quantum computing to solve problems in the following areas: data mining, life sciences, network analysis, and chemical modeling studies."
The Jiuzhang computer was developed by a team of Chinese scientists led by Pan Jianwei, a professor of physics at the University of Science and Technology of China (USTC) — known as the father of quantum computing in China — with the aim of using quantum computing. To solve the problems we face in the world.
"The research team has succeeded in taking another step in solving practical problems with quantum computers of the current architecture," said Pan Jianwei.
Quantum computing is an interdisciplinary field that includes aspects of computer science, physics, and mathematics and uses quantum mechanics to solve complex problems faster than classical computers. The field of quantum computing includes research on devices and development of applications.
Quantum computers can also solve some problems faster than conventional computers by exploiting quantum mechanical effects such as superposition and quantum interference.
How fast is Jiuzhang's computer?
The Chinese quantum computer (Jiuzhang) gained great international recognition in 2020 and achieved a new quantum supremacy by performing a computational operation in just 200 seconds, and is the world's fastest non-quantum or classical computation. On a computer, it takes more than 2.5 billion years.
But this year, the research team succeeded in using the Jiuzhang computer to implement some popular artificial intelligence algorithms and speed up their performance, which is a major breakthrough in the field of quantum computing.
The research team uses computers to implement and accelerate the performance of my (random search) and (simulated annealing) algorithms, which are widely used in the field of artificial intelligence and pose a great challenge to traditional supercomputers. The researchers decided to solve the problem using more than 200,000 samples.
With current technology, the world's fastest supercomputer takes an estimated 700 seconds to process each sample, which means it would take up to five years to process the same number of samples.
But the Juezhang computer has a computing time of less than a second, making it 180 million times faster than the world's current fastest supercomputer.
What are the advantages of using the Jiuzhang supercomputer?
Quantum computing differs from traditional computing. (bit) A bit is represented by the number "zero" or "one" as a unit of basic information. Then there are limitations in the data representation process, which limit the performance of computers that handle complex data tasks.
While quantum computing relies on a (qubit) quantum bit that can be represented as a "zero", "one", or both simultaneously, allowing all possibilities to be represented simultaneously, its strength lies in solving complex problems and operations.
The United States is also researching quantum supercomputers and has found that the subnuclear particles that power quantum computers are easily destroyed and have a short lifespan, making them vulnerable to interference from the environment. For this reason, quantum computers operate in isolated environments and at extremely low temperatures.
But the Jiuzhang computer, named after a 2,000-year-old Chinese mathematical text, uses light as a physical medium for the calculations and, unlike other quantum computers, doesn't have to operate in a closed environment. at extremely low temperatures and can work steadily for a long time.
Optical quantum computers use quantum light sources that emit compressed pulses of light and qubit equivalents corresponding to continuous actuator modes such as position or momentum.
The team deliberately used some of the advanced algorithms in use today to demonstrate the benefits of quantum computing, as the research showed that even early quantum computers had significant advantages over classical computers.
According to the research team, this new achievement of the Jiuzhang computer can also help researchers apply technology to solve problems in many fields today, especially the problems faced by machine learning algorithms. In data mining, it can help solve the problems that computers think are most important. Effective market is difficult at the moment.
