iqm.error_reduction_tools.twirling.twirling_modifiers.process_measure_gate(operation, new_circuit, registers, drop_final_rz=True)#

Process a measurement gate: record readout twirling character and append.

Determines the net readout twirling character (‘I’ or ‘X’) from the parity of accumulated π rotations on the measured qubit, stores it in registers.rot_chars, and appends the measurement operation.

Parameters:

  • operation (CircuitOperation) – The measurement CircuitOperation to process.

  • new_circuit (TwirledCircuit) – The new circuit being built.

  • registers (TrackingRegisters) – Tracking registers for π-rotation state and readout characters.

  • drop_final_rz (bool) – If True (default), any pending virtual-Z before measurement is silently dropped. If False, raises NotImplementedError.

Return type:

None
