Title:
QUANTUM COMPUTING TASK PROCESSING METHOD AND SYSTEM, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/082436
Kind Code:
A1
Abstract:
A quantum computing task processing method and system, and a computer device, which relate to the field of quantum technology. The quantum computing task processing method comprises: performing transformation processing on input quantum states of n+m quantum bits by means of a parameterized quantum circuit (PQC), wherein the n+m quantum bits comprise n task bits and m auxiliary bits, n and m being positive integers (21); measuring output quantum states of the n+m quantum bits, so as to obtain a bit character string of the n+m quantum bits (22); when an auxiliary sub-string meets a post-selection condition and the PQC is not converged, updating parameters of the PQC on the basis of the output quantum states of the n task bits (23); and when the auxiliary sub-string meets the post-selection condition and the circuit is converged, acquiring a computing result on the basis of the output quantum states of the n task bits (24). By means of the method, the expression capability of a PQC of a variational task is improved, thereby improving the execution effect of the variational task.
