Experts have spoken highly of a significant computing breakthrough achieving quantum computational advantage announced by a Chinese research team on Friday. The team established a quantum computer prototype, named "Jiuzhang," via which up to 76 photons were detected. This achievement marks that China has reached the first milestone on the path to full-scale quantum computing -- a quantum computational advantage, also known as "quantum supremacy," which indicates an overwhelming quantum computational speedup. No traditional computer can perform the same task in a reasonable amount of time, and the speedup is unlikely to be overturned by classical algorithmic or hardware improvements, according to the team.
