Jiuzhang achieves quantum supremacy

A photonic quantum computer, which harnesses particles of light, or photons, performed a calculation that’s impossible for a conventional computer, researchers in China report

The Jiuzhang quantum computer has achieved quantum supremacy (quantum advantage), according to the study “Quantum computational advantage using photons”, published in Science on 3 December 2020. Pan Jian-Wei, professor, University of Science and Technology of China, explains how the Jiuzhang quantum computer was used.
