AND.compose

AND.compose(other, qubits=None, clbits=None, front=False, inplace=False)

Compose circuit with other circuit or instruction, optionally permuting wires.

other can be narrower or of equal width to self.

Parameters

  • other (qiskit.circuit.Instruction or QuantumCircuit or BaseOperator) – (sub)circuit to compose onto self.

  • qubits (list[Qubit|int]) – qubits of self to compose onto.

  • clbits (list[Clbit|int]) – clbits of self to compose onto.

  • front (bool) – If True, front composition will be performed (not implemented yet).

  • inplace (bool) – If True, modify the object. Otherwise return composed circuit.

Returns

the composed circuit (returns None if inplace==True).

Return type

QuantumCircuit

Raises

  • CircuitError – if composing on the front.

  • QiskitError – if other is wider or there are duplicate edge mappings.

Examples

>>> lhs.compose(rhs, qubits=[3, 2], inplace=True)
