China is changing the rules of the quantum computing game.
Scientists in China report that their latest quantum computer solved an extremely complex mathematical problem in a millionth of a second. This is 20 billion years faster than the world's fastest supercomputer could handle the same task.
The JiuZhang 3 prototype also broke the record set by its predecessor, increasing the computing speed by a factor of one million. This is reported in an article published in the peer-reviewed journal Physical Review Letters. The research team is led by Pan Jianwei, a leading scientist in China's national quantum research program.
The first Jiuzhang computer was created by Pan's team in 2020. This series uses photons as a physical means for computing. After increasing the number of photons from 76 to 113 in the first two versions of the machine, Pan's team reached 255 photons in the latest version.
The researchers used JiuZhang 3 to solve a complex Gaussian boson sampling problem that simulates the behavior of light particles passing through a maze of crystals and mirrors. In the experiment, the team stated that JiuZhang 3 solved the problem with the highest sampling complexity in a millionth of a second.
The fastest classical Frontier supercomputer developed in the United States would take more than 20 billion years to complete the same task.
China, the United States, and other countries are racing to achieve "quantum supremacy." However, they use different methods to achieve this goal.
Despite their speed, these machines are not yet ready to replace conventional computers. At the moment, they can only work in a secure environment for short periods of time and perform very specific tasks.
