qml.transforms.convert_to_numpy_parameters

convert_to_numpy_parameters(tape)

Transforms a circuit to one with purely numpy parameters.

Parameters

tape (QuantumScript) – a circuit with parameters of any interface

Returns

The transformed circuits along with a dummy post-processing function.

Return type

tuple[List[QuantumScript], function]

Examples:

>>> ops = [qml.S(0), qml.RX(torch.tensor(0.1234), 0)]
>>> measurements = [qml.state(), qml.expval(qml.Hermitian(torch.eye(2), 0))]
>>> circuit = qml.tape.QuantumScript(ops, measurements)
>>> [new_circuit], _ = convert_to_numpy_parameters(circuit)
>>> new_circuit.circuit
[S(wires=[0]),
RX(0.1234000027179718, wires=[0]),
state(wires=[]),
expval(Hermitian(array([[1., 0.],
        [0., 1.]], dtype=float32), wires=[0]))]

If the component’s data does not need to be transformed, it is left uncopied.

>>> circuit[0] is new_circuit[0]
True
>>> circuit[1] is new_circuit[1]
False
>>> circuit[2] is new_circuit[2]
True
>>> circuit[3] is new_circuit[3]
False
