Quantum circuit simulation method and device, equipment and storage medium

***The invention provides a simulation method, device and equipment of a quantum circuit and a storage medium, and relates to the field of computers, in particular to the field of quantum calculation and quantum simulation. According to the specific implementation scheme, initial signal processing information t (x) corresponding to a target quantum signal processing circuit is obtained; under the condition that it is determined that the initial signal processing information t (x) does not meet the processing condition of the quantum signal processing information, target signal processing information p * (x) corresponding to the initial signal processing information t (x) is determined, and the target signal processing information p * (x) is used for estimating the processing effect of the target quantum signal processing circuit on signal processing of a signal point x; and obtaining a target processing parameter of a target quantum signal processing circuit by using the target signal processing information p
