China's Quantum Computing Advancements: A Comparative Analysis with the US.

Chinese quantum computer Jiuzhang has been found to be 180 million times faster than classical computers in solving a problem that is challenging for classical computers. The researchers used Jiuzhang to implement and accelerate two algorithms commonly used in AI, random search and simulated annealing. Jiuzhang uses light as the physical medium for calculation and does not need to work sealed in extremely low temperatures like other quantum computers.
