qml.load

load(quantum_circuit_object, format, **load_kwargs)

Load external quantum assembly and quantum circuits from supported frameworks into PennyLane templates.

Note

For more details on which formats are supported please consult the corresponding plugin documentation: https://pennylane.ai/plugins.html

Example:

>>> qc = qiskit.QuantumCircuit(2)
>>> qc.rz(0.543, [0])
>>> qc.cx(0, 1)
>>> my_circuit = qml.load(qc, format='qiskit')

The my_circuit template can now be used within QNodes, as a two-wire quantum template.

>>> @qml.qnode(dev)
>>> def circuit(x):
>>>     qml.RX(x, wires=1)
>>>     my_circuit(wires=(1, 0))
>>>     return qml.expval(qml.Z(0))

Parameters

• quantum_circuit_object – the quantum circuit that will be converted to a PennyLane template

• format (str) – the format of the quantum circuit object to convert from

• **load_kwargs – keyword arguments to pass when converting the quantum circuit using the plugin. See below for details about supported keyword arguments.

Keyword Arguments

measurements (list[MeasurementProcess]) – the list of PennyLane measurements that overrides the terminal measurements that may be present in the imput circuit. Currently, only supported for Qiskit’s QuantumCircuit.

Returns

the PennyLane template created from the quantum circuit object

Return type
