Jiuzhang quantum computer solves complex tasks in less than a second, a feat that the world's fastest classical supercomputer would take nearly 5 years to accomplish.
A group of researchers announces a significant breakthrough in quantum computing. Jiuzhang quantum computer is found capable of tackling various complex computational tasks including data exploration and exploitation, biological information processing, network analysis, and chemical modeling.
Jiuzhang quantum computer has been identified as capable of handling multiple complex computational tasks.Pan Jianwei, a leading physicist from the University of Science and Technology of China, is dubbed the 'Quantum Father' in the country and heads the research team. His team's research has been published in the Physical Review Letters journal. The research team states: 'Our work represents a step forward in addressing real-world computational problems using current quantum computers.'
In an era where big data is rapidly growing, global data volume doubles every two years. Pan Jianwei remarks: 'Failing to fully exploit the resources from this vast data is futile.' Currently, the development of traditional computer models has reached a limit, and supercomputers consume a large amount of energy. According to him, the importance of 'Jiuzhang' lies in its ability to enhance computing power without significantly increasing energy consumption.
Failing to fully exploit the resources from this vast data is pointlessA group of scientists has successfully solved complex computational equations that were previously challenges for traditional computers. They used over 200,000 samples to solve these problems.
During the experiment, a notable advancement occurred as researchers used quantum computers to accelerate solutions for two commonly used algorithms in artificial intelligence: random search and optimization.
The world's fastest conventional supercomputer takes 700 seconds to analyze each computational sample, meaning it would take nearly 5 years to process the same amount of samples. However, the Jiuzhang quantum computer solved this algorithm in less than a second.
The world's fastest conventional supercomputer takes 700 seconds to analyze each computational sample.In traditional computing, a bit represents a single state: either 0 or 1, serving as the basic unit of information. In quantum computing, however, a qubit can describe a more complex state. A qubit can represent both 0 and 1 simultaneously - this is the simplest representation in quantum mathematics.
Because quantum computers can explore all possibilities simultaneously in basic information, theory suggests they are much faster and more powerful than everyday conventional computers we use in daily life.
The Jiuzhang quantum computer - named after an ancient Chinese mathematical manuscript from around 2,000 years agoThe Jiuzhang quantum computer - named after an ancient Chinese mathematical manuscript from around 2,000 years ago, utilizes photon light as a physical medium for computation. Unlike other quantum computers, it does not require operation at extremely low temperatures and can operate stably for longer durations.
However, quantum computers only function in extremely cold environments and are isolated to avoid noise and errors. The size of the atomic particles on which quantum computers depend is very small, and their lifespan is very short, making the operation of quantum computers fragile.

However, China's 'Jiuzhang' quantum computer represents a breakthrough on the path to universal quantum computing, known as 'quantum advantage', ensuring superior speed in this field. No conventional computer can perform the same task in a reasonable time, and improvements in the algorithms or hardware of conventional computers are unlikely to surpass that impressive speed.
