Abstract
A computation device generates a plan that controls an oscillator configured to perform parametric oscillation such that an intensity of a pump signal that is input to the oscillator increases from a first value according to an elapsed time and then decreases to a second value, and a magnitude of a detuning between a resonance frequency of the oscillator and an oscillation frequency of the oscillator increases from a third value according to the elapsed time and then decreases to a fourth value. The computation device generates a quantum state of the oscillator by controlling the oscillator based on the plan. The computation device performs computation using the generated quantum state.
