Title:
量子測定ノイズの除去方法、システム、電子機器、及び媒体
Document Type and Number:
Japanese Patent JP7199489
Kind Code:
B2
Abstract:
A method includes: determining a maximum number Z of times for executing a measuring device continuously; operating the quantum computer to perform, for each integer k in a set {0, 1, . . . , K} comprising Z integers, M1 quantum computation processes to generate, for each quantum computation process, of the M1 quantum computation processes, an intermediate measurement result, wherein, in each quantum computation process, the quantum computer is operated to generate an n-qubit quantum state p, and continuously execute the measuring device for k+1 times, so as to obtain the intermediate measurement result of the quantum computation process; operating a classical computer to compute an average measurement result of the M1 quantum computation processes; and operating the classical computer to determine, by means of Neumann series based on the average measurement result(s) corresponding to all the integers k, unbiased estimation of a computed result of eliminating quantum measurement noise.
