Quantum computational advantage using photons

Zhong et al. sent 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer and sampled the output using 100 high-efficiency single-photon detectors. By obtaining up to 76-photon coincidence, yielding a state space dimension of about 10^30, they measured a sampling rate that is about 10^14-fold faster than using state-of-the-art classical simulation strategies and supercomputers.
