qml.ftqc.measure_z

measure_z(wires, reset=False, postselect=None)

Perform a mid-circuit measurement in the Z basis. The measurements are performed using the 0, 1 convention rather than the ±1 convention.

Note

This function dispatches to qml.measure

For more details on the results of mid-circuit measurements and how to use them, see qml.measure.

Parameters

• wires (Wires) – The wire to measure.

• reset (Optional[bool]) – Whether to reset the wire to the $|0 \rangle$ state after measurement.

• postselect (Optional[int]) – Which basis state to postselect after a mid-circuit measurement. None by default. If postselection is requested, only the post-measurement state that is used for postselection will be considered in the remaining circuit.

Returns

The mid-circuit measurement result linked to the created MidMeasureMP.

Return type

MeasurementValue

Raises

QuantumFunctionError – if multiple wires were specified
