deprecations_primitives:
|
|
- |
|
|
Primitive V1 implementations and V1-exclusive non-versioned type aliases are now
|
|
deprecated in favor of their V2 counterparts. The deprecation is extended to the
|
|
following classes implementing V1 interfaces:
|
|
|
|
* :class:`.Estimator`, in favor of the V2 equivalent, :class:`.StatevectorEstimator`
|
|
* :class:`.Sampler`, in favor of the V2 equivalent, :class:`.StatevectorSampler`
|
|
* :class:`.BackendEstimator`, in favor of the V2 equivalent, :class:`.BackendEstimatorV2`
|
|
* :class:`.BackendSampler`, in favor of the V2 equivalent, :class:`.BackendSamplerV2`
|
|
|
|
As well as the following non-versioned type aliases:
|
|
|
|
* :class:`.BaseEstimator`, alias for :class:`.BaseEstimatorV1`
|
|
* :class:`.BaseSampler`, alias for :class:`.BaseSamplerV1`
|
|
|
|
This deprecation does NOT affect the explicitly-versioned :class:`BaseEstimatorV1`
|
|
and :class:`BaseSamplerV1` abstract
|
|
interface definitions or related result and job classes.
|
|
|
|
In addition, the following utility functions are deprecated:
|
|
|
|
* :func:`.init_circuit`, to initialize a circuit from a :class:`.Statevector`,
|
|
use :meth:`.QuantumCircuit.initialize` instead,
|
|
* :func:`.init_observable`, use the constructor of :class:`.SparsePauliOp` instead,
|
|
* :func:`.final_measurement_mapping`, use :meth:`.QuantumCircuit.layout` and
|
|
:meth:`.SparsePauliOp.apply_layout` to adjust an operator for a layout.
|
|
Otherwise, use ``mthree.utils.final_measurement_mapping``.
|
|
See `Mthree Utility functions <https://qiskit-extensions.github.io/mthree/apidocs/utils.html>`__
|
|
for details.
