class boulderopalscaleup.experiments.TransmonAnharmonicity(*, transmon, frequencies=None, anharmonicity=-200000000.0, recycle_delay_ns=10000, shot_count=400, spectroscopy_waveform=None, measure_waveform=None, run_mixer_calibration=False, update='auto')

Parameters for running a transmon anharmonicity experiment.

Variables

transmon (str) – The reference for the transmon to target.
frequencies (LinspaceIterable or RangeIterable or CWSIterable or None , optional) – The frequencies at which to scan, in Hz. Defaults to a scan based on the transmon’s frequency and anharmonicity.
anharmonicity (float , optional) – The guessed anharmonicity of the transmon, in Hz. Used to determine the scan frequencies if not provided. Defaults to -200 MHz.
recycle_delay_ns (int , optional) – The delay between consecutive shots, in nanoseconds. Defaults to 10,000 ns.
shot_count (int , optional) – The number of shots to take. Defaults to 400.
spectroscopy_waveform (ConstantWaveform or None , optional) – The waveform to use in the spectroscopy pulse. Defaults to a constant waveform with a duration of 2,000 ns and an amplitude of 1.5 times the transmon’s x_vp.
measure_waveform (ConstantWaveform or None , optional) – The waveform to use for the measurement pulse. Defaults to the measurement defcal.
run_mixer_calibration (bool , optional) – Whether to run mixer calibrations before running a program. Defaults to False.
update ( "auto" or "off" or "prompt" , optional) – How the device should be updated after an experiment run. Defaults to auto.
