EurekAlert  January 14, 2020 The inability of conventional electronic architectures to efficiently solve large combinatorial problems motivates the development of novel computational hardware. Researchers at MIT present the Photonic Recurrent Ising Sampler (PRIS), a heuristic method tailored for parallel architectures allowing fast and efficient sampling from distributions of arbitrary Ising problems. Since the PRIS relies on vector-to-fixed matrix multiplications, implementing of the PRIS in photonic parallel networks will realize operations at an unprecedented speed…read more.
