QUANTUM INFORMATION PROCESSING METHOD FOR OBTAINING DIFFERENTIAL OR NON-ADIABATIC COUPLING OF ENERGY, CLASSICAL COMPUTER, QUANTUM COMPUTER, HYBRID SYSTEM, AND QUANTUM INFORMATION PROCESSING PROGRAM

WIPO Patent Application WO/2022/234862

A1

A classical computer according to the present invention configures a first objective function. The classical computer calculates a circuit parameter θ* for a quantum circuit U^(θ) that minimizes the first objective function. The classical computer configures a second objective function that holds the circuit parameter θ* as a constant and holds an orbital parameter κ as a variable. The classical computer calculates an orbital parameter κ* for minimizing the second objective function. Next, a quantum computer performs a quantum measurement of an expected value including a differential from a quantum circuit U^θ* and a position parameter x of a Hamiltonian H^(x, κ*), and acquires measurement results of the quantum measurement. On the basis of the measurement results of the quantum measurement, the classical computer calculates a differential of the energy corresponding to a Hamiltonian H^(x).
