qml.transforms.convert_to_numpy_parameters

convert_to_numpy_parameters(circuit)

Transforms a circuit to one with purely numpy parameters.

Parameters

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

Returns

A circuit with purely numpy parameters

Return type

QuantumScript

pennylane.tape.Unwrap modifies a QuantumScript in place instead of creating a new class. It will also set all parameters on the circuit, not just ones that need to be unwrapped.

>>> 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
