Abstract: A parity checking method and apparatus for a qubit, a superconducting quantum chip, an electronic device, and a storage medium are provided. The method includes: configuring a measurement system for a qubit excited state measurement environment, the measurement system including: a first data qubit, a second data qubit, and an auxiliary qubit; determining a first operational frequency parameter of the first data qubit; determining a second operational frequency parameter of the second data qubit; determining a third operational frequency parameter of the auxiliary qubit; determining a logic gate matching the qubit excited state measurement environment based on the first operational frequency parameter, the second operational frequency parameter, and the third operational frequency parameter; and checking parity of a qubit in the qubit excited state measurement environment according to the logic gate.

Abstract: A quantum circuit includes: a qubit, a resonant cavity, and a feeder, the resonant cavity being coupled to the qubit, and the feeder being coupled to the qubit. The feeder is configured to feed an initialization signal to the qubit, the initialization signal being a modulation signal used for causing a frequency of the qubit to generate a vibration. The vibration causes an equivalent state exchange to occur between the qubit and the resonant cavity, and an excited state of the qubit is initialized to a ground state by using the resonant cavity.
