Entanglement and quantum discord in optically coupled coherent Ising machines
Entanglement and quantum discord in optically coupled coherent Ising machines
We present analytical and numerical simulation results for squeezing, entanglement, and quantum discord in a dissipatively coupled coherent Ising machine (CIM). Both analytical solutions and numerical simulation results, which are obtained with positive-P, truncated-Wigner and truncated-Husimi representations for the density operator, predict the presence of entanglement and quantum discord, below …
