class AcquireMode(value)

Bases: Enum

The AcquireMode is used to specify the type of acquisition at the level of the control hardware.

Note that different backends will only allow selected acquisition modes.

• RAW: Returns the time-series acquisition data for each shot

• SCOPE: Returns the time-series acquisition data where each point is averaged over the number of shots

• INTEGRATOR: Down-conversion and integration of the acquisition data has occurred on the hardware so that a

  single data point is returned for each shot

INTEGRATOR = 'integrator'

RAW = 'raw'

SCOPE = 'scope'

class PostProcessType(value)

Bases: Enum

PostProcessType is used in a PostProcessing instruction to determine how readouts should be processed. It describes a type of classical post-processing:

• DOWN_CONVERT: Down-converts the readout measurement, should only be used along the axis ProcessAxis.TIME.

• MEAN: Takes an average over the given axis.

• LINEAR_MAP_COMPLEX_TO_REAL: Maps the (complex) measured value onto a (real) z-projection using a supplied

  linear mapping.

• DISCRIMINATE: Converts a z-projection to a classical bit by comparison with a supplied discrimination threshold.

DISCRIMINATE = 'discriminate'

DOWN_CONVERT = 'down_convert'

LINEAR_MAP_COMPLEX_TO_REAL = 'linear_map_real'

MEAN = 'mean'

MUL = 'mul'

class ProcessAxis(value)

Bases: Enum

ProcessAxis is used during classical post-processing of readouts. It specifies the axis which the post-processing should occur on. Often used in conjunction with the AcquireMode to determine the correct method for post-processing.

• TIME: Instructs the post-processing to be performed over the time-series data returned from a readout.

• SEQUENCE: Instructs the post-processing to be performed over the shots.

SEQUENCE = 'sequence'

TIME = 'time'
