  • Publication number: 20220310212
    Abstract: A method is implemented to select a calculator for performing given processing using a quantum algorithm or a combined algorithm of a classical algorithm and the quantum algorithm. The method comprises a calculation operation, a selection operation, and a control operation. The calculation operation calculates a quantum bit or a quantum volume for performing the given processing using the quantum algorithm, or for a portion of the quantum algorithm when performing the given processing using the combined algorithm. The selection operation selects a calculator for performing the given processing based on the quantum bit or the quantum volume. The control operation generates a control signal to be transmitted to the quantum calculator when the selected calculator includes a quantum calculator. The control signal may correspond to an instruction that initiates the quantum calculator to start the quantum algorithm.
