| Abstract(in English) | The coherent Ising machine (CIM) has attracted attention as one of the most effective Ising computing architectures for solving large scale optimization problems because of its scalability and high-speed computational ability. Because the CIM is a non-equilibrium open-dissipative system, the theories and techniques of classical thermodynamic equilibrium Ising spin systems cannot be directly applied to the CIM. Now our research group attempts to adapt these theories and techniques to the CIM. Here we focus on the CDMA (Code Division Multiple Access) multiuser detector, which is one of canonical frustrated models of Ising computation. We derive a macroscopic equation to estimate a critical value of the spreading factor for achieving low bit error rate as a function of the pump rate in the CIM-implemented CDMA multiuser detector. |
