The latest progresses about optical quantum computer were announced by Prof. Pan Jianwei team at University of Science and Technology of China. They have achieved ten photon entanglement, and built a quantum simulator for high-efficiency multiphoton boson sam-pling.Bose sampling can be used for demonstrating quan-tum supremacy. The researchers have developed 9×9 mode multiphoton interferometers with 99% transmis-sion rate and actively demultiplexed single-photon sources based on a quantum dot–micropillar with sim-ultaneously high efficiency, purity and indistinguishabil-ity. The three-photon, four-photon and five-photon Bose samples were tested and verified. The sampling rates were 4.96 kHz, 151 Hz and 4 Hz, respectively, which are over 24000 times faster than previous experiments.This is the first single photon-based quantum photonic machines which are provably faster for the bos-on-sampling task than the early classical computer, lay-ing a foundation for the "quantum supremacy ".
