deprecations:

|
- |
|
|
To streamline the structure of Qiskit's gates and operations, the :mod:`qiskit.extensions`
|
|
module is pending deprecation and will be deprecated in a future release.
|
|
The following objects have been moved to :mod:`qiskit.circuit.library`
|
|
|
|
* :class:`~.library.DiagonalGate`,
|
|
* :class:`~.library.HamiltonianGateGate`,
|
|
* :class:`~.library.Initialize`,
|
|
* :class:`~.library.Isometry`,
|
|
* :class:`~.library.generalized_gates.mcg_up_diag.MCGupDiag`,
|
|
* :class:`~.library.UCGate`,
|
|
* :class:`~.library.UCPauliRotGate`,
|
|
* :class:`~.library.UCRXGate`,
|
|
* :class:`~.library.UCRYGate`,
|
|
* :class:`~.library.UCRZGate`,
|
|
* :class:`~.library.UnitaryGate`.
|
|
|
|
These instructions have already been deprecated in this release,
|
|
|
|
* :class:`~.SingleQubitUnitary`, instead use :class:`.library.UnitaryGate`,
|
|
* :class:`~.extensions.Snapshot`, which has been superseded by Qiskit Aer's save instructions,
|
|
|
|
along with their circuit methods
|
|
|
|
* :meth:`.QuantumCircuit.snapshot`,
|
|
* :meth:`.QuantumCircuit.squ`.
|
|
|
|
In addition, the following circuit methods are pending deprecation
|
|
|
|
* :meth:`.QuantumCircuit.diagonal`,
|
|
* :meth:`.QuantumCircuit.hamiltonian`,
|
|
* :meth:`.QuantumCircuit.isometry` and :meth:`.QuantumCircuit.iso`,
|
|
* :meth:`.QuantumCircuit.uc`,
|
|
* :meth:`.QuantumCircuit.ucrx`,
|
|
* :meth:`.QuantumCircuit.ucry`,
|
|
* :meth:`.QuantumCircuit.ucrz`.
|
|
|
|
Since the entire module is pending deprecation, so is :class:`.ExtensionError`.
