Integrated Photonics for Large Scale Quantum Computing

In the past few years, a number of research groups around the world have demonstrated small scale, photonic quantum information processing using approaches like Gaussian Boson Sampling, which can function with the current “Noisy, Intermediate Scale” (NISQ) quantum devices. At the same time, the industry partner and other groups have proposed a variety of large-scale photonic quantum computing architectures. These large-scale architectures have yet to be realized in practice and will require large investments to bring to fruition.
