Time-domain characterization and correction of on-chip distortion of control pulses in a quantum processor
Time-domain characterization and correction of on-chip distortion of control pulses in a quantum processor
We introduce Cryoscope, a method for sampling on-chip baseband pulses used to dynamically control qubit frequency in a quantum processor. We specifically use Cryoscope to measure the step response of the dedicated flux control lines of two-junction transmon qubits in circuit QED processors with the temporal resolution of the room-temperature …
