Abstract: A method includes: obtaining a set of characterizing equations for a quantum gate to be benchmarked; in response to the set of characterizing equations including another quantum gate, determining whether the another quantum gate has been benchmarked as trusted; in response to the another quantum gate having been benchmarked as trusted, successively performing a quantum gate operation on each characterizing equation in the set of characterizing equations to obtain, for each characterizing equation, a corresponding measurement result; for each characterizing equation, determining whether the measurement result for the characterizing equation meets an expected result in the characterizing equation for characterization; and in response to the measurement results for each characterizing equation in the set of characterizing equations meeting the expected result, benchmarking the quantum gate to be benchmarked as trusted.

Abstract: 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 result; 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.
