Chinese Quantum Computer based on photons

Quantum light sources for the Gaussian Boson Sampling (GBS) [Zhong, 2020]

Gaussian Boson Sampling (GBS) is a protocol developed by Hamilton et al.  in 2017 that uses single mode squeezed states (SMSS) as a nonclassical resource with outputs patterns in the photon number basis [1].
