qiskit.pulse.builder.control_channels

control_channels(*qubits)

Return ControlChannel for qubit on the active builder backend.

Return the secondary drive channel for the given qubit – typically utilized for controlling multi-qubit interactions.

Examples:

from qiskit import pulse
from qiskit.test.mock import FakeOpenPulse2Q

backend = FakeOpenPulse2Q()
with pulse.build(backend):
    assert pulse.control_channels(0, 1) == [pulse.ControlChannel(0)]

Note

Requires the active builder context to have a backend set.

Parameters

qubits (Iterable[int]) – Tuple or list of ordered qubits of the form (control_qubit, target_qubit).

Return type

List[ControlChannel]

Returns

List of control channels associated with the supplied ordered list of qubits.
