Jiuzhang's quantum computing system can calculate 100 trillion times faster the world's fastest existing supercomputer.
A research team including the famous Chinese quantum physicist Pan Jianwei (announce) on December 4, 2020 a vital breakthrough, achieving a quantum computational advantage.
This (achieve) marks that China has reached the first great breakthrough on the path to full-scale quantum computing—a quantum computational advantage, also known "quantum supremacy".
No traditional computer can perform the same task in reasonable amount of time, and the speedup is unlikely to (remove) by classical hardware improvements, according to the team.
In the study, GBS was used to provide a (high) efficient way of demonstrating quantum computational speedup in solving some tasks.
The team also said the new model processes about 10 billion times as fast as the 53-qubit quantum computer developed by Google and that the breakthrough (be) the result of 20 years of effort, which has overcome several major technological blocks.
(compare) with conventional computers, Jiuzhang is currently just a "champion in one single area," but (it) super-computing capacity has application potential in areas such as graph theory, machine learning and quantum chemistry, according to the team.
