Identity gate corresponds to a single-qubit gate wait cycle, and should not be optimized or unrolled (it is an opaque gate). Can be applied to a :class:`~qiskit.circuit.QuantumCircuit` with the :meth:`~qiskit.circuit.QuantumCircuit.i` and :meth:`~qiskit.circuit.QuantumCircuit.id` methods. **Matrix Representation:** .. math:: I = \begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix} **Circuit symbol:** .. code-block:: text ┌───┐ q_0: ┤ I ├ └───┘ Ndt)durationunitlabelcVtddg|||dS)zCreate new Identity gate.idr)rr r N)super__init__)selfrr r __class__s ]/granary/edev/quantum/lib/python3.11/site-packages/qiskit/circuit/library/standard_gates/i.pyrzIGate.__init__4s. q"EH4PPPPPF annotatedctS)aReturne the inverse gate (itself). Args: annotated: when set to ``True``, this is typically used to return an :class:`.AnnotatedOperation` with an inverse modifier set instead of a concrete :class:`.Gate`. However, for this class this argument is ignored as this gate is self-inverse.
