China shatters world record in quantum computing
China shatters world record in quantum computing
Researchers at the University of Science and Technology of China have unveiled Jiuzhang 4.0 — the latest prototype of their quantum supercomputer.
Jiuzhang 4.0 can manage 3,000 photons — a dramatic leap from the 255 photons handled by its predecessor — signaling major advances in photon generation, optical circuitry, and error management.
Tested on Gaussian Boson Sampling, Jiuzhang 4.0 completed the model in just 25 microseconds — a task that would take a classical supercomputer longer than the age of the universe to solve.
