Document Type and Number:
Japanese Patent JP7043651
Kind Code:
B2
Abstract:
The present application discloses a method and apparatus for evaluating a quantum gate in a superconducting circuit, a device and a storage medium, which relate to the field of quantum computations. The specific scheme may include: acquiring a Hamiltonian corresponding to a superconducting circuit structure, wherein the superconducting circuit structure may include computation qubits and a coupler disposed between two of the computation qubits and coupled with the two of the computation qubits respectively; performing decoupling processing for the coupler on the Hamiltonian to obtain the processed Hamiltonian representing a coupling strength between the computation qubits; and obtaining, based on the processed Hamiltonian, a first data processing rule that takes circuit parameters of the superconducting circuit structure as input parameters, wherein a degree of a difference between a target quantum gate and a theoretical quantum gate can be obtained based on the first data processing rule.
