qml.from_qasm_file

from_qasm_file(qasm_filename: str)[source]

Loads quantum circuits from a QASM file using the converter in the PennyLane-Qiskit plugin.

Example:

>>> my_circuit = qml.from_qasm("hadamard_circuit.qasm")

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.PauliZ(0))
Parameters

qasm_filename (str) – path to a QASM file containing a valid quantum circuit

Returns

the PennyLane template created based on the QASM file

Return type
