QuantumCircuit.control(num_ctrl_qubits=1, label=None, ctrl_state=None)

Control this circuit on num_ctrl_qubits qubits.

প্যারামিটার

• num_ctrl_qubits (int) -- The number of control qubits.

• label (str) -- An optional label to give the controlled operation for visualization.

• ctrl_state (str or int) -- The control state in decimal or as a bitstring (e.g. '111'). If None, use 2**num_ctrl_qubits - 1.
