We report phase-programmable Gaussian boson sampling (GBS) which produces up to 113 photon detection events out of a 144-mode photonic circuit. A new high-brightness and scalable quantum light source is developed, exploring the idea of stimulated emission of squeezed photons, which has simultaneously near-unity purity and efficiency. This GBS is programmable by tuning the phase of the input squeezed states. The obtained samples are efficiently validated by inferring from computationally…

This work reports on a boson-sampling device operated with a bright solid-state source of single-photon Fock states with high photon-number purity, and a demultiplexed source between 1 and 2 orders of magnitude more efficient than current heralded multiphoton sources based on spontaneous parametric down-conversion.

Regimes of Classical Simulability for Noisy Gaussian Boson Sampling.

It is shown that, for most linear-optical architectures, where photon loss increases exponentially with the circuit depth, noisy GBS loses its quantum advantage in the asymptotic limit, and delineate intermediate-sized regimes where GBS devices might considerably outperform classical computers for modest noise levels.
