China's quantum computer is 10 billion times more powerful than a Google device

A photonic quantum computer, which uses light particles to operate, has performed a calculation that it cannot

a regular computer can handle it.This event is called “quantum supremacy”; it was previously achieved only in 2019 on Google’s quantum computer. However, the company's device is based on superconducting materials, not photons.

The new quantum computer can perform verya complex calculation in 200 seconds that would take more than half a billion years on the world's fastest classical computer. The new device, called Jiuzhang, consists of a complex array of optical devices that move photons around. It includes light sources, hundreds of beam splitters, dozens of mirrors and hundreds of photon detectors.

This is the first independent confirmation of Google's claim that you can truly achieve quantum supremacy. It's exciting.

To check the functionality of your computerThe researchers used bosonic sampling. The device generated a distribution of numbers that is extremely difficult to reproduce on a classical computer.  When working with a large number of photons and channels, a quantum computer will produce a distribution of numbers that is too complex for a classical computer.

The researchers explained that using quantumadvantages scientists will be able to solve complex problems faster. This could lead to faster research, computation and discovery that scientists can reach more easily.
