qml.devices.preprocess.no_sampling

no_sampling(tape, name='device')

Raises an error if the tape has finite shots.

Parameters

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

• name (str) – name to use in error message.

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]

This transform can be added to forbid finite shots. For example, default.qubit uses it for adjoint and backprop validation.
