Claim 17:
18. The parity checking apparatus according to claim 16, wherein to determining the parity checking result of the qubit in the qubit excited state measurement environment according to the second Hamiltonian parameter comprises:
converting the second Hamiltonian parameter when a phase of an input state remains unchanged, to obtain a third Hamiltonian parameter;
determining a state of the auxiliary qubit according to the third 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.
