QUANTUM CIRCUIT SIMULATION METHOD AND DEVICE, APPARATUS, AND STORAGE MEDIUM

摘要

A quantum circuit simulation method and device, an apparatus, and a storage medium are provided, which are related to a field of quantum simulation computation. The specific implementation is: obtaining, based on a quantum circuit containing n qubits, an n-order pure state corresponding to the quantum circuit; determining, based on the quantum circuit, a (k, k)-order gate tensor representing a quantum gate, on which a contraction processing is to be performed with the n-order state tensor; transforming the contraction processing between the n-order state tensor and the (k, k)-order gate tensor into a processing between matrices which can be expressed in a classic computer and reduce a computation amount in the classic computer, to obtain a processing resu and using the processing result as a result of the contraction processing between the n-order state tensor and the (k, k)-order gate tensor, to complete simulation of the quantum circuit.
