Novel computing machines, based on coherent dynamics in the network of lasers or parametric oscillators, have been actively studied as heuristic algorithms for NP-hard optimization problems and quantum simulators for many body systems. The conference covers fundamental principles, algorithms and applications, as well as physical implementation of such coherent network computing.


  • Coherent Ising machines
  • Coherent XY machines
  • Quantum and physical annealing systems
  • Recurrent neural network and reservoir computing
  • Combinatorial optimization, continuous optimization and Boltzmann sampling algorithms
  • Quantum simulation of many body systems
  • Physics of quantum-to-classical crossover, quantum Darwinism and quantum chaos
  • Bifurcation theory and quantum phase transition
