Release Notes_Terra
===================

.. _Release Notes_Terra_0.25.2:

Terra 0.25.2
============

.. _Release Notes_Terra_0.25.2_Prelude:

Prelude
-------

.. releasenotes/notes/prepare-0.25.2-69e6db49ca39da3f.yaml @ b'57a96b84c58337a4c1b83c141219972e0cf2a2be'

Qiskit Terra 0.25.2 is a small patch release, fixing several bugs found in the 0.25 series.


.. _Release Notes_Terra_0.25.2_Bug Fixes:

Bug Fixes
---------

.. releasenotes/notes/dd-pg-10833-ddddee68ffd913c4.yaml @ b'382514f9a82967244b8dc4c6364d0fb6b9808d8f'

- Fixed a bug in the :class:`.PadDynamicalDecoupling` transpiler pass which
would cause the pass to fail if a circuit contained a pulse gate
calibration for one of the gates in the decoupling sequence. Fixed `#10833
<https://github.com/Qiskit/qiskit/issues/10833>`_.

.. releasenotes/notes/fix-clifford-from-diagonal-7708654373bd5b8b.yaml @ b'a29b959af14789bdfef6e0f4298481dd2d6d889e'

- Fixed a bug where :meth:`~.Clifford.from_matrix` and :meth:`~.Clifford.from_operator`
do not fail with non-Clifford diagonal operators (matrices) and return incorrect
Clifford objects. This has been corrected so that they raise an error in the cases.
Fixed `#10903 <https://github.com/Qiskit/qiskit-terra/issues/10903>`__

.. releasenotes/notes/fix-flow-cregbundle-transpiled-482979d57382b1dc.yaml @ b'6046106caf348824d698912f30c9dd6cee3dddf9'

- Fixed an issue with the matplotlib based visualization in the
:meth:`.QuantumCircuit.draw` method and the :func:`~.circuit_drawer`
function when visualizing circuits that had control flow instructions.
Previously in some situations, especially with a layout set, the output
visualization could have put gates inside a control flow block on the
wrong wires in the visualization.
Fixed `#10601 <https://github.com/Qiskit/qiskit-terra/issues/10601>`__

.. releasenotes/notes/fix-gate-direction-d8bc96b62b27dba8.yaml @ b'93b571bc87f3375b93f2474088fbdfebdc9b31db'

- Fixes a bug with the :class:`.GateDirection` transpiler pass where it
unnecessarily raised an exception for input DAGs with more than 1
quantum register.
Fixed `#10824 <https://github.com/Qiskit/qiskit/issues/10824>`__.

.. releasenotes/notes/fix-qasm2-final-comment-f0904c3e13215a00.yaml @ b'946aa28604bac5f3afde95581afc24a521c06d48'

- OpenQASM 2 programs that end in comments with no terminating newline character will now parse
successfully. Fixed `#10770 <https://github.com/Qiskit/qiskit/issues/10770>`__.

.. releasenotes/notes/fix-qpy-repeated-controlled-gates-e19fc4ee65a22756.yaml @ b'e4b04718f42754b63bc240579d0ad2406980bd15'

- Fixed a bug in QPY serialization (:mod:`qiskit.qpy`) where if a circuit contained
multiple instances of parametrized controlled gates of the same class (not custom),
the parameter values from the first instance were used to build the gate definitions
of subsequent instances. The gates were rendered correctly despite this bug because
the correct parameter values were stored, but not used to build the gates. Fixed
`#10735 <https://github.com/Qiskit/qiskit-terra/issues/10735>`__.

.. releasenotes/notes/fix_pauli_new_style_bit-0704933127b4debe.yaml @ b'cc0f30cc8a2ea2f10d1eaef49ae53fe27f48f412'

- The class :class:`.Pauli` now support creation from :class:`.QuantumCircuit`
that use new-style :class:`.Bit`.

.. releasenotes/notes/sampler-with-no-measure-6cd3a05555187b58.yaml @ b'391647504ab88cc569e8f678b0053bc1bf5bf0c9'

- Add early validation for :class:`.BaseSampler` when input :class:`.QuantumCircuit` does not
have measurements.

.. releasenotes/notes/support-empty-delete-for-pauli-16c5c5fae890c16c.yaml @ b'9361538393340f4b3d4b80cc190c6143974dbbbf'

- Passing an empty list to the methods :meth:`.Pauli.delete`, :meth:`.PauliList.delete`,
and :meth:`.PauliTable.delete` now returns a copy of the original object instead of throwing an error.
