This paper presents an experiment demonstrating quantum computational advantage using Gaussian boson sampling (GBS) with 50 single-mode squeezed states (SMSSs) and a 100-mode ultralow-loss interferometer. The experiment achieves a sampling rate of ~10^14 times faster than state-of-the-art simulations and supercomputers, with an output state space dimension of ~10^30. The results validate the quantum computational advantage by showing that the output distribution is highly non-classical and cannot be explained by thermal states, distinguishable photons, or uniform distributions. The experiment also demonstrates that the quantum state is robust to decoherence and can be operated at room temperature.
The GBS protocol uses Gaussian states generated by parametric down-conversion (PDC) and exploits the linear optical network to produce highly entangled photon-number and path-entangled states. The output distribution is related to a matrix function called Torontonian, which is computationally hard to calculate. The experiment shows that the output distribution is highly non-classical and cannot be explained by classical simulations. The results are validated against various hypotheses, including thermal states, distinguishable photons, and uniform distributions.
