Researchers at the University of Science and Technology of China have developed the Jiuzhang 4.0 photonic quantum computing prototype, which manipulates 3,050 photons and sets a new record.
Researchers at the University of Science and Technology of China announced the launch of the Jiuzhang 4.0 prototype. The device uses 1,024 squeezed-state inputs across an 8,176-mode interferometric network.
The prototype completed a Gaussian boson sampling task in 25 microseconds. The task would take the world's fastest supercomputer, El Capitan, more than 10^42 years to finish.
The research team was led by Pan Jianwei in collaboration with several Chinese institutes. The results were published in Nature on Wednesday.
Compared with the earlier Jiuzhang 3 system, the new machine expands photon processing capability by more than ten times.
