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…
Quantum correlation in degenerate optical parametric oscillators with mutual injections
Kenta Takata, Alireza Marandi, Yoshihisa Yamamoto
We theoretically and numerically study the quantum dynamics of two degenerate optical parametric oscillators with mutual injections. The cavity mode in the optical coupling path be…
Binary phase oscillation of two mutually coupled semiconductor lasers
Shoko Utsunomiya, Naoto Namekata, Kenta Takata +3
A two-site Ising model is implemented as an injection-locked laser network consisting of a single master laser and two mutually coupled slave lasers. We observed ferromagnetic and…
Network of Time-Multiplexed Optical Parametric Oscillators as a Coherent Ising Machine
Alireza Marandi, Zhe Wang, Kenta Takata +2
Finding the ground states of the Ising Hamiltonian [1] maps to various combinatorial optimization problems in biology, medicine, wireless communications, artificial intelligence, a…
Data Search by a Laser Ising Machine with Gradual Pumping or Coupling
Kenta Takata, Yoshihisa Yamamoto
We study two operational schemes for a coherent Ising machine based on an injection-locked laser network. These schemes gradually increase the pumping rate or the mutual coupling a…
