Efficient sampling of ground and low-energy Ising spin configurations with a coherent Ising machine

no code implementations9 Mar 2021 Edwin Ng, Tatsuhiro Onodera, Satoshi Kako, Peter L. McMahon, Hideo Mabuchi, Yoshihisa Yamamoto

We show that the nonlinear stochastic dynamics of a measurement-feedback-based coherent Ising machine (MFB-CIM) in the presence of quantum noise can be exploited to sample degenerate ground and low-energy spin configurations of the Ising model.

Efficient simulation of ultrafast quantum nonlinear optics with matrix product states

no code implementations11 Feb 2021 Ryotatsu Yanagimoto, Edwin Ng, Logan G. Wright, Tatsuhiro Onodera, Hideo Mabuchi

Ultra-short pulses propagating in nonlinear nanophotonic waveguides can simultaneously leverage both temporal and spatial field confinement, promising a route towards single-photon nonlinearities in an all-photonic platform.
