Operation

class Operation

Bases: abc.ABC

Quantum Operation Interface Class. For objects that can be added to a QuantumCircuit. These objects include Gate, Reset, Barrier, Measure, and operators such as Clifford. The main purpose is to add an Operation to a QuantumCircuit without synthesizing it before the transpilation.

Example

Add a Clifford and a Toffoli gate to a QuantumCircuit.

from qiskit import QuantumCircuit
from qiskit.quantum_info import Clifford, random_clifford
 
qc = QuantumCircuit(3)
cliff = random_clifford(2)
qc.append(cliff, [0, 1])
qc.ccx(0, 1, 2)
qc.draw()
