FluxPulseGate_SmoothConstant

FluxPulseGate_SmoothConstant#

class iqm.pulse.gates.cz.FluxPulseGate_SmoothConstant(parent, name, locus, calibration_data, builder)#

Bases: FluxPulseGate

Flux pulse gate implementation realized as a 3-part pulse sequence, consisting of |cosine rise|Constant|cosine fall|. Otherwise, works similar to FluxPulseGate.

Parameters:

  • flux_pulses – mapping from flux channel name to its flux pulse

  • rz – mapping from drive channel name to the virtual z rotation angle, in radians, that should be performed on it

  • parent (QuantumOp)

  • name (str)

  • locus (Locus)

  • calibration_data (OILCalibrationData)

  • builder (ScheduleBuilder)

Module: iqm.pulse.gates.cz

rise_wave#

Waveform, rise part of the 3-pulse sequence to be played with qubit and coupler gates.

alias of CosineRiseFlex

symmetric: bool = True#

True iff the implementation is symmetric in its locus components. Only meaningful if arity != 1, and the locus components are of the same type.

fall_wave#

Waveform, fall part of the 3-pulse sequence to be played with qubit and coupler gates.

alias of CosineFallFlex

Parameters shared by all FluxPulseGate classes. Inheriting classes may override this if there’s a need for additional calibration parameters.
