.. _Release Notes_0.12.0_Aer_Prelude:
Prelude
-------
.. releasenotes/notes/0.12/prepare-0.12-0da477fc0492ca5d.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
The Qiskit Aer 0.12.0 release highlights are:
* Added a new GPU tensor network simulator based on
`cuTensorNet <https://docs.nvidia.com/cuda/cuquantum/cutensornet/index.html>`__
* Added a new :class:`~.AerDensityMatrix` class to the :mod:`qiskit_aer.quantum_info` module
* Greatly improving the runtime performance of the :class:`~.AerSimulator` and the legacy
:class:`~.QasmSimulator`, :class:`~.StatevectorSimulator`, and :class:`~.UnitarySimulator`
classes by directly converting the input :class:`~.QuantumCircuit` objects to an internal
C++ representation instead of first serializing the circuit to a :class:`~.QasmQobj`. This
improvement will be most noticeable for circuits with a small number of qubits or parameterized
circuits using the ``parameter_binds`` keyword argument.
.. _Release Notes_0.12.0_Aer_New Features:
New Features
------------
.. releasenotes/notes/0.12/add-NoiseModel-from_backendproperties-1a3d6d976133a661.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Added a new class method :meth:`~.NoiseModel.from_backend_properties` to
the :class:`NoiseModel`. This enables constructing a new :class:`~.NoiseModel`
from a :class:`~qiskit.providers.BackendProperties` object. Similar functionality used
to be present in the :meth:`.NoiseModel.from_backend` constructor,
however it was removed since a :class:`~qiskit.providers.BackendProperties` object alone
doesn't contain sufficient information to create a :class:`~.NoiseModel`
object.
.. releasenotes/notes/0.12/add-aer-density-matrix-e2439120b24c91c9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Added a new class, :class:`~.AerDensityMatrix`, to the :mod:`qiskit_aer.quantum_info`
module. This class is used to provide the same interface to the
upstream :class:`~qiskit.quantum_info.DensityMatrix` class in Qiskit but backed by
Qiskit Aer's simulation.
.. releasenotes/notes/0.12/add-grouping-fcc4fad69ccdac26.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Added a new keyword argument, ``abelian_grouping``, to
the :class:`~.Estimator`. This argument is used to control whether the
:class:`~.Estimator` will group the input observables into qubit-wise
commutable observables which reduces the number of circuit executions
required to compute the expectation value and improves the runtime
performance of the :class:`~.Estimator`. By default this is set to
``True``.
.. releasenotes/notes/0.12/add_initialize_density_matrix-a72b1a614b09726e.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- ``AerState`` has a new method ``initialize_density_matrix()`` that sets a density matrix
to ``AER::QV::DensityMatrix``. This method will be called in ``q.i.states.DensityMatrix``
to initialize its data with ``ndarray``. ``initialize_density_matrix()`` has a boolean
argument that specifies copy or share of ``ndarray`` data. If the data is shared with
C++ and python, the data must not be collected in python while C++ accesses it.
.. releasenotes/notes/0.12/own_assembler-0c76e67a054bd12c.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The overhead for running simulations with :meth:`~.AerSimulator.run`
(for all simulator backend classess) has been greatly reduced. This was
accomplished by no longer internally serializing
:class:`~qiskit.circuit.QuantumCircuit` objects into
:class:`~qiskit.qobj.QasmQobj` and instead the
:class:`~qiskit.circuit.QuantumCircuit` object directly to
an internal C++ circuit structure used for simulation. This improvement
is most noticeable for simulations of circuts with a small number of qubits
or parameterized circuits using the ``parameter_binds`` keyword argument
of :meth:`~.AerSimulator.run`.
Note that pulse simualation (via the now deprecated :class:`~.PulseSimulator`)
and DASK-based simulation still use the internal serialization and will
not see this performance improvement.
.. releasenotes/notes/0.12/own_assembler-0c76e67a054bd12c.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Added a new method to the :class:`~.AerJob`, :meth:`~.AerJob.circuits`, which
returns a list of :class:`~qiskit.circuit.QuantumCircuit` objects. This method returns
``None`` if Qobj is used for simulation.
.. releasenotes/notes/0.12/support_kraus-ec31e636c6793b8c.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- :class:`.AerState` and :class:`.AerStatevector` now support applying :class:`~qiskit.quantum_info.Kraus` operators.
In :class:`.AerStatevector`, one of the Kraus operators is applied randomly to the quantum state based on the error probabilities.
.. releasenotes/notes/0.12/tensor_network_gpu-e8eb3e40be3c35f7.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Added a new simulation method based on NVIDIA's `cuTensorNet <https://docs.nvidia.com/cuda/cuquantum/cutensornet/index.html>`__
APIs of cuQuantum SDK. This provides a GPU accelerated general tensor
network simulator that can simulate any quantum circuit, by internally
translating the circuit into a tensor network to perform the simulation.
To use this simulation method, set ``method="tensor_network"`` and
``device="GPU"`` when initializing an :class:`~.AerSimulator` object.
For example::
from qiskit_aer import AerSimulator
tensor_net_sim = AerSimulator(method="tensor_network", device="GPU")
This method supports both statevector and density matrix simulations.
Noise simulation can also be done with a density matrix single shot
simulation if there are not any :class:`~.SaveStatevector` operations
in the circuit.
This new simulation method also supports parallelization with multiple GPUs and
MPI processes by using tensor network slicing technique. However, this type of
simulation will likely take a very long time if the input circuits are
complicated.
.. releasenotes/notes/0.12/use_specified_bla_vendor-ca0322e993378048.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The ``BLA_VENDOR`` environment variable can now be specified to use a
different BLAS library when building Qiskit Aer from source. By default
if this is not specified OpenBLAS will be used by default. If
the BLAS library specified in `BLA_VENDOR`` can not be found then the
Cmake build process will stop.
.. _Release Notes_0.12.0_Aer_Known Issues:
Known Issues
------------
.. releasenotes/notes/0.12/use_conan_1.x-f12570e2cfc8bb26.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- This release of Qiskit Aer is not compatible with the Conan 2.X release
series. If you are building Qiskit Aer from source manually ensure that
you are using a Conan 1.x release. Compatibility with newer versions
of Conan will be fixed in a future release. You can refer to
issue `#1730 <https://github.com/Qiskit/qiskit-aer/issues/1730>`__ for
more details.
.. _Release Notes_0.12.0_Aer_Upgrade Notes:
Upgrade Notes
-------------
.. releasenotes/notes/0.12/add-grouping-fcc4fad69ccdac26.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The default behavior of the :class:`~.Estimator` primitive will now
group the input observable into qubit-wise commutable observables.
The grouping reduces the number of circuits to be executed and improves
the performance. If you desire the previous behavior you can initialize
your :class:`~.Estimator` instance with the keyword argument
``abelian_grouping=False``.
.. releasenotes/notes/0.12/delete-args-and-methods-in-primitives-8013546db867e849.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Removed the usage of primitives with the context manager and the initialization with circuits,
(observables only for Estimator), and parameters
which has been deprecated in the Qiskit Terra 0.22.0 release in October 2022.
.. releasenotes/notes/0.12/own_assembler-0c76e67a054bd12c.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The behavior of :meth:`~.AerSimulator.run` method has changed when invalid
or otherwise unsimulatable :class:`~.QuantumCircuit` objects are passed as
an input. Previously, in these cases the :meth:`~.AerSimulator.run` method
would return an :class:`~.AerJob` whose :meth:`~.AerJob.result` method would
return a :class:`~.Result` with the ``ERROR`` or ``PARTIAL COMPLETED``
(depending on whether all the circuit inputs or only some were invalid or not).
Starting in this release instead of returning a result object with these statuses
an exception will be raised instead. This change was necessary because
of the performance improvements by no longer internally serializing the
:class:`~.QuantumCircuit` objects to a Qobj before passing it to C++, instead
the direct conversion from :class:`~.QuantumCircuit` now errors directly when
trying to simulate a circuit Qiskit Aer is unable to execute. If you desire the
previous behavior you can build Qiskit Aer in standalone mode and manually
serialize your :class:`~.QuantumCircuit` objects to a JSON representation of
the :class:`~.QasmQobj` which you then pass to the standalone Aer binary
which will retain the previous behavior.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- A deprecated method :meth:`add_nonlocal_quantum_error` in :class:`~.NoiseModel` has been
removed. No alternative method is available. If you want to add non-local quantum errors,
you should write a transpiler pass that inserts your own quantum error into a circuit,
and run the pass just before running the circuit on Aer simulator.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The :meth:`.NoiseModel.from_backend` now has changed not to accept ``BackendProperties``
object as a ``backend`` argument. Use newly added :meth:`.NoiseModel.from_backend_properties`
method instead.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- A deprecated ``standard_gates`` argument broadly used in several methods and functions
(listed below) across :mod:`~.noise` module has been removed.
* :meth:`NoiseModel.from_backend` and :func:`noise.device.basic_device_gate_errors`
* :func:`kraus_error`, :func:`mixed_unitary_error`, :func:`pauli_error` and
:func:`depolarizing_error` in :mod:`noise.errors.standard_errors`
* :meth:`QuantumError.__init__`
No alternative means are available because the user should be agnostic about
how the simulator represents noises (quantum errors) internally.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The constructor of :class:`~.QuantumError` has now dropped the support of deprecated
json-like input for ``noise_ops`` argument.
Use the new styple input for ``noise_ops`` argument instead, for example,
.. code-block:: python
from qiskit.circuit.library import IGate, XGate
from qiskit_aer.noise import QuantumError
error = QuantumError([
((IGate(), [1]), 0.9),
((XGate(), [1]), 0.1),
])
# json-like input is no longer accepted (the following code fails)
# error = QuantumError([
# ([{"name": "I", "qubits": [1]}], 0.9),
# ([{"name": "X", "qubits": [1]}], 0.1),
# ])
Also it has dropped deprecated arguments:
* ``number_of_qubits``: Use ``QuantumCircuit`` to define ``noise_ops`` instead.
* ``atol``: Use :attr:`QuantumError.atol` attribute instead.
* ``standard_gates``: No alternative is available (users should not too much care about
internal representation of quantum errors).
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The deprecated :mod:`noise.errors.errorutils` module has been entirely removed
and no alternatives are available.
All functions in the module were helper functions meant to be used
only for implementing functions in :mod:`~.noise.errors.standard_errors`
(i.e. they should have been provided as private functions)
and no longer used in it.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The deprecated :mod:`utils.noise_remapper` have been entirely removed and no alternatives
are available since the C++ code now automatically truncates and remaps noise models
if it truncates circuits.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- All deprecated functions (:func:`pauli_operators` and :func:`reset_operators`)
and class (:class:`NoiseTransformer`) in :mod:`utils.noise_transformation` module
have been removed, and no alternatives are available.
They were in fact private functions/class used only for implementing
:func:`approximate_quantum_error` and should not have been public.
.. releasenotes/notes/0.12/remove-qobj-684e68e99b212973.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The previously deprecated ``qobj`` argument name of the
:class:`~.AerSimulator` and :class:`~.PulseSimulator` classes'
:meth:`~.AerSimulator.run` method has now been removed. This argument
name was deprecated as part of the Qiskit Aer 0.8.0 release and has
been by the ``circuits`` and ``schedules`` argument name respectively.
.. releasenotes/notes/0.12/remove-setup_requires-751a406e2782885e.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Aer's ``setup.py`` has been updated to no longer attempt to make calls to ``pip`` to
install build requirements, both manually and via the ``setup_requires`` option in
``setuptools.setup``. The preferred way to build Aer is to use a `PEP 517 <https://peps.python.org/pep-0517/>`__-compatible
builder such as:
.. code-block:: text
pip install .
This change means that a direct call to ``setup.py`` will no longer work if the
build requirements are not installed. This is inline with modern Python packaging
guidelines.
.. _Release Notes_0.12.0_Aer_Deprecation Notes:
Deprecation Notes
-----------------
.. releasenotes/notes/0.12/deprecate-37-b3ec705b9f469b0b.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Support for running Qiskit Aer with Python 3.7 support has been deprecated
and will be removed in a future release. This means
starting in a future release you will need to upgrade the Python
version you're using to Python 3.8 or above.
.. releasenotes/notes/0.12/deprecate-pulse-simulator-27cde3ece112c346.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The :class:`~.PulseSimulator` backend has been deprecated and will be
removed in a future release. If you're using the :class:`~.PulseSimulator`
backend to perform pulse level simulation, instead you should use the
`Qiskit Dynamics <https://qiskit.org/documentation/dynamics/>`__ library
instead to perform the simulation. Qiskit Dynamics provides a more
flexible and robust pulse level simulation framework than the
:class:`~.PulseSimulator` backend.
.. releasenotes/notes/0.12/own_assembler-0c76e67a054bd12c.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The :meth:`~.AerJob.qobj` method of the :class:`AerJob` class is
now deprecated and will be removed in a future release. The use of
the qobj format as input to :meth:`~.AerSimulator.run` has been
deprecated since qiskit-aer 0.9.0 and in most cases this method
would return ``None`` now anyway. If you'd like to get the input
to the ``run()`` method now you can use the :meth:`~.AerJob.circuits`
method instead, which will return the :class:`~.QuantumCircuit`
objects that were simulated in the job.
.. releasenotes/notes/0.12/remove-deprecated-noise-functions-52128d161d3327e9.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- A ``warnings`` argument broadly used in several methods and functions
across :mod:`~.noise` module has been deprecated in favor of
the use of filtering functions in Python's standard ``warnings`` library.
.. _Release Notes_0.12.0_Aer_Bug Fixes:
Bug Fixes
---------
.. releasenotes/notes/0.12/fix-ndarray-contiguity-e903d0fda4744100.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Fixed an issue when creating a new :class:`~.AerStatevector` instance
from a ``numpy.ndarray`` that had non-contiguous memory. Previously,
this would result in unexpected behavior (and a potential error) as
the :class:`~.AerStatevector` assumed the input array was contiguous. This
has been fixed so that memory layout is checked and the ``numpy.ndarray``
will be copied internally as a contiguous array before using it.
.. releasenotes/notes/0.12/fix-split-cregs-5b5494a92c4903e7.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Fixed an issue with the :class:`.Sampler` class where it would previously
fail if the input :class:`~.QuantumCircuit` contained multiple
multiple classical registers.
Fixed `#1679 <https://github.com/Qiskit/qiskit-aer/issues/1679>`__
.. releasenotes/notes/0.12/fix_batch_execution-da4d88dbee26731b.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The bits count of classical register used on the GPU was not set before
calculating free available memory for chunks that causes infinite loop.
So this fix set bits count before allocating chunks if batch shots
execution is enabled.
.. releasenotes/notes/0.12/fix_tensor_network_not_installed-a23b8ef65e6e643e.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Fix build errors and test errors when enabling GPU but disabling cuQuantum.
.. releasenotes/notes/0.12/mps_fix_apply_measure-84c29a728ae0e717.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- Fixed an issue in the matrix product state simulation method (i.e.
setting the keyword argument ``method="matrix_product_state"`` when
initializing an :class:`~.AerSimulator` object) where the simulator
would incorrectly sort the qubits prior to performing measurment
potentially resulting in an infinite loop. This has been fixed so
the measurement of the qubits occurs in the order of the current MPS
structure and then sorting afterwards as a post-processing step. This also
will likely improve the performance of the simulation method and enable
more accurate representation of entangled states.
Fixed `#1694 <https://github.com/Qiskit/qiskit-aer/issues/1694>`__
.. releasenotes/notes/0.12/support_break_and_continue_gates-bf30316fcacd4b6b.yaml @ b'2377d2efb48d18aab73df121924a1446310297de'
- The :class:`.AerSimulator` backend with methods:
* ``statevector``
* ``density_matrix``
* ``matrix_product_state``
* ``stabilizer``
now report that they support ``break_loop`` and ``continue_loop`` instructions when used
as backends for the Terra :func:`~qiskit.compiler.transpile` function. The simulators
already did support these, but had just not been reporting it.
.. _Release Notes_IBMQ_0.20.2:
IBM Q Provider 0.20.2
=====================
This release removes the overly restrictive version constraints set in the
requirements for the package added in 0.20.1. For the 0.20.1 the only dependency
that was intended to have a version cap was the ``requests-ntlm`` package as its
new release was the only dependency which currently has an incompatibility with
``qiskit-ibmq-provider``. The other version caps which were added as part of
0.20.1 were causing installation issues in several environments because it made
the ``qiskit-ibmq-provider`` package incompatible with the dependency versions
used in other packages.
