Claim 9:
10. The method according to claim 9, wherein the iSwap gate comprises a first iSwap gate configured for the first data qubit and the auxiliary qubit and a second iSwap 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 fourth Hamiltonian parameter of the measurement system according to the first iSwap gate and the second iSwap gate;
adjusting the fourth Hamiltonian parameter based on a Hadamard gate in the measurement system, to obtain a fifth Hamiltonian parameter;
converting the fifth Hamiltonian parameter when a phase of an input state remains unchanged, to obtain a sixth Hamiltonian parameter;
determining a state of the auxiliary qubit according to the sixth Hamiltonian parameter;
determining, when the state of the auxiliary qubit is that the auxiliary qubit flips, that the qubit is in an even excited state; and
determining, when the state of the auxiliary qubit is that the auxiliary qubit remains unchanged, that the qubit is in an odd excited state.
