Claim 5:
6. The method according to claim 5, wherein the control Pauli-Z gate comprises a first control Pauli-Z gate configured for the first data qubit and the auxiliary qubit and a second control Pauli-Z gate configured for the second data qubit and the auxiliary qubit; and
checking parity of the qubit in the qubit excited state measurement environment according to the logic gate comprises:
determining a first Hamiltonian parameter of the measurement system according to the first control Pauli-Z gate and the second control Pauli-Z gate;
adjusting the first Hamiltonian parameter based on a Hadamard gate in the measurement system, to obtain a second Hamiltonian parameter; and
determining a parity checking result of the qubit in the qubit excited state measurement environment according to the second Hamiltonian parameter.
