qml.devices.preprocess.validate_device_wires

validate_device_wires(tape, wires=None, name='device')

Validates that all wires present in the tape are in the set of provided wires. Adds the device wires to measurement processes like StateMP that are broadcasted across all available wires.

Parameters

• tape (QuantumTape or QNode or Callable) – a quantum circuit.

• wires=None (Optional[Wires]) – the allowed wires. Wires of None allows any wires to be present in the tape.

• name="device" (str) – the name of the device to use in error messages.

Returns

The unaltered input circuit. The output type is explained in qml.transform.

Return type

qnode (QNode) or quantum function (Callable) or tuple[List[QuantumTape], function]

Raises

WireError – if the tape has a wire not present in the provided wires.
