qoqo.operations.MeasureQubit

class qoqo.operations.MeasureQubit

Measurement gate operation.

This Operation acts on one qubit writing the result of the measurement into a readout. The classical register for the readout needs to be defined in advance by using a Definition operation.

Parameters:

qubit (int) – The measured qubit.
readout (string) – The classical register for the readout.
readout_index (int) – The index in the readout the result is saved to.
