We realize quantum computational advantage in a Gaussian Boson Sampling (GBS) experiment. We inject 25 two mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random matrix. We rule out thermal states, distinguishable photons, and uniform distribution hypotheses. This GBS machine can sample 14 orders of magnitude faster than classical supercomputer.
In this paper, we present an overview of the devolvement of niobium nitride (NbN)-based superconducting nanowire single-photon detector (SNSPD) array for applications in SIMIT. These applications include high-speed interleaved nanowire arrays for optical quantum communication, large-active-area arrays for light detection and ranging (LIDAR), and free-space-coupled arrays for LIDAR and imaging. A recent development in fiber-array-coupled SNSPD array for quantum information processing is also presented.
