Title:
QUANTUM CIRCUIT OPTIMIZATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE, COMPUTER-READABLE STORAGE MEDIUM AND COMPUTER PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2024/021819
Kind Code:
A1
Abstract:
The present application relates to quantum computing technology. Provided are a quantum circuit optimization method and apparatus, and an electronic device, a computer-readable storage medium and a computer program product. The method comprises: converting, into a unitary matrix to be processed, a quantum circuit to be optimized, and performing iterative decomposition on said unitary matrix, so as to obtain a first number of quantum-bit uniform control gates; decomposing each quantum-bit uniform control gate into a second number of quantum-bit diagonal unitary matrices and a third number of single-quantum-bit gates; on the basis of a connected graph, determining a matching quantum circuit corresponding to each quantum-bit diagonal unitary matrix; integrating a second number of matching quantum circuits and the third number of single-quantum-bit gates, so as to obtain a target quantum circuit of each quantum-bit uniform control gate; and connecting a first number of target quantum circuits, so as to obtain an optimized quantum circuit.
