Title:
CONTROL DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/047797
Kind Code:
A1
Abstract:
A control device comprising: a coefficient calculation unit which calculates a coefficient on the basis of information relating to the calculation of the gradient of an objective function; a measurement planning unit which generates, on the basis of the calculated coefficient, a sequence illustrating quantum operations at given points in time for certain qubits of a quantum circuit provided in a quantum computer, and which transmits information indicating the generated sequence to the quantum computer; and a measurement aggregation unit which receives, from the quantum computer, information indicating expected values that represent an assessment result, and which calculates the gradient by means of an aggregation based on the expected values.
