  • Publication number: 20220292235
    Abstract: An arithmetic apparatus includes a control unit that changes a first weighting coefficient assigned to a constraint term included in Hamiltonian so that the first weighting coefficient changes differently from a second weighting coefficient assigned to an objective term included in the Hamiltonian in process of reducing quantum fluctuations to obtain a ground state of the Hamiltonian used for solving a combinatorial optimization problem.

  • Publication number: 20220147596
    Abstract: The efficiency of quantum annealing on an LHZ model is improved. An arithmetic apparatus includes an arithmetic unit configured to adjust an intensity schedule function in quantum annealing of a constraint term expressed by many-body interactions in an LHZ model by a hybrid algorithm that uses a value of the intensity schedule function at one time point or each of a plurality of time points as a variational parameter.
