I have been trying to make a gate in qiskit in terms of the basic gates, but I keep on getting an error when I apply it to a circuit.
This is my gate:
class LGate(Gate): def __init__(self, label=None): super().__init__('l', 1, , label=label) def _define(self): from qiskit.circuit.quantumcircuit import QuantumCircuit from qiskit.circuit.library import U3Gate q = QuantumRegister(1, 'q') qc = QuantumCircuit(q, name=self.name) rules = [ (U3Gate(pi, 0, pi), [q], ) ] qc._data = rules self.definition = qc
Of course this is just an X gate, but I was just trying a basic example.
Running the program:
circ = QuantumCircuit(2) circ.l(0) print(circ)
AttributeError: 'QuantumCircuit' object has no attribute 'l'
