Abstract
A method for processing a frequency control signal includes providing a square wave pulse to a target qubit, and controlling, after a first time elapses from an end time of the square wave pulse, the target qubit to rotate around a Y axis by a first target distance. The first time has a value that is variable. The method includes performing, after a second time elapses from the first time, a QST measurement on the target qubit and reconstructing a density matrix of the target qubit based on the QST measurement to obtain a phase parameter value of the target qubit associated with the value of the first time. Further, the method includes varying the first time and repeating the QST measurement in response to values of the first time to obtain phase parameter values associated with the values of the first time; and adjusting the frequency control signal accordingly.
