QUANTUM CALCULATION CONTROL PROGRAM, QUANTUM CALCULATION CONTROL METHOD, AND INFORMATION PROCESSING DEVICE

The calculation time in quantum calculations is reduced.A computer causes a first quantum calculator among a plurality of quantum calculators that calculate a quantum state of a system subject to calculation to repeat calculations of the quantum state under a first calculation condition (for example, θ = θ0) a first number of times (N times). In addition, the computer calculates first energy (for example, E0s) of the system, based on calculation results of the first quantum calculator for a second number of times (sN times) less than the first number of times, and information on the system. Then, the computer causes a second quantum calculator among the plurality of quantum calculators to start the calculations of the quantum state under a second calculation condition (for example, θ = θ1s) designated based on the first energy, during the calculations under the first calculation condition.
