Experimental investigation of performance differences between Coherent Ising Machines and a quantum annealer
Ryan Hamerly, Takahiro Inagaki, Peter L. McMahon +20
Physical annealing systems provide heuristic approaches to solving NP-hard Ising optimization problems. Here, we study the performance of two types of annealing machines--a commerc…
Performance evaluation of coherent Ising machines against classical neural networks
Yoshitaka Haribara, Hitoshi Ishikawa, Shoko Utsunomiya +2
The coherent Ising machine is expected to find a near-optimal solution in various combinatorial optimization problems, which has been experimentally confirmed with optical parametr…
Boltzmann sampling for an XY model using a non-degenerate optical parametric oscillator network
Yutaka Takeda, Shuhei Tamate, Yoshihisa Yamamoto +3
We present an experimental scheme of implementing multiple spins in a classical XY model using a non-degenerate optical parametric oscillator (NOPO) network. We built an NOPO netwo…
Simulating the classical XY model with a laser network
Shuhei Tamate, Yoshihisa Yamamoto, Alireza Marandi +2
Drawing fair samples from the Boltzmann distribution of a statistical model is a challenging task for modern digital computers. We propose a physical implementation of a Boltzmann…
Truncated Wigner function theory of coherent Ising machines based on degenerate optical parametric oscillator network
Daiki Maruo, Shoko Utsunomiya, Yoshihisa Yamamoto
We present the quantum theory of coherent Ising machines based on networks of degenerate optical parametric oscillators (DOPOs). In a simple model consisting of two coupled DOPOs,…
A 16-bit Coherent Ising Machine for One-Dimensional Ring and Cubic Graph Problems
Kenta Takata, Alireza Marandi, Ryan Hamerly +6
Many tasks in our modern life, such as planning an efficient travel, image processing and optimizing integrated circuit design, are modeled as complex combinatorial optimization pr…
