class iqm.error_reduction_tools.twirling.twirling_modifiers.TrackingRegisters(virtual_z=<factory>, extra_phi=<factory>, extra_pi=<factory>, sqg_number=<factory>, already_used_sqg=<factory>, rot_chars=<factory>)

Bases: object

Container for tracking registers during circuit randomization.

Attributes

virtual_z	Track pending Z rotations per qubit.
extra_phi	Track phase values for π rotations.
extra_pi	Track count of π rotations per qubit.
sqg_number	Number of single-qubit gates per qubit.
already_used_sqg	Number of already processed gates per qubit.
rot_chars	Readout twirling character(s) per qubit ('I' or 'X').

Methods

__eq__(other)	Return self==value.
__repr__()	Return repr(self).
