Data acquisition for allXY experiment varying delay after a measurement pulse to characterise resonator depletion time: https://arxiv.org/pdf/1604.00916. Passive resonator depletion time: Time it takes the process by which photons inside a resonator dissipate over time without any external intervention. After a measurement is performed, photons remain in the resonator and qubits errors induced if trying to drive the qubit by leftover photons due to the coupling resonator-qubit inducing a shift in the qubit frequency. This experiment is used to characterise the resonator depletion time by waiting an increased delay time until the allXY pattern looks right.
