### \_\_call\_\_

<span id="qiskit.synthesis.XXDecomposer.__call__" />

`__call__(unitary, basis_fidelity=None, approximate=True)`

Fashions a circuit which (perhaps approximately) models the special unitary operation `unitary`, using the circuit templates supplied at initialization as `embodiments`. The routine uses `basis_fidelity` to select the optimal circuit template, including when performing exact synthesis; the contents of `basis_fidelity` is a dictionary mapping interaction strengths (scaled so that $CX = RZX(\pi/2)$ corresponds to $\pi/2$) to circuit fidelities.

**Parameters**

* **unitary** ([*Operator*](qiskit.quantum_info.Operator "qiskit.quantum_info.Operator") *or ndarray*) – $4 \times 4$ unitary to synthesize.
* **basis\_fidelity** ([*dict*](https://docs.python.org/3/library/stdtypes.html#dict "(in Python v3.12)") *or*[*float*](https://docs.python.org/3/library/functions.html#float "(in Python v3.12)")) – Fidelity of basis gates. Can be either (1) a dictionary mapping `XX` angle values to fidelity at that angle; or (2) a single float `f`, interpreted as `{pi: f, pi/2: f/2, pi/3: f/3}`. If given, overrides the basis\_fidelity given at init.
* **approximate** ([*bool*](https://docs.python.org/3/library/functions.html#bool "(in Python v3.12)")) – Approximates if basis fidelities are less than 1.0 .

**Returns**

Synthesized circuit.

# Qiskit 1.0 release notes

## 1.0.1

<span id="relnotes-1-0-1-prelude" />

### Prelude

Qiskit 1.0.1 is a patch release fixing a small number of bugs identified in the Qiskit 1.0.0 release.

<span id="relnotes-1-0-1-bug-fixes" />

<span id="id2" />

### Bug Fixes

* Fixed a bug in the conversion of custom pulse instructions to the legacy [`qiskit.qobj`](/api/qiskit/qobj#module-qiskit.qobj "qiskit.qobj") format. The bug was introduced in Qiskit 1.0.0 and caused conversion of instructions with custom pulse shapes to raise an error. After the fix, the conversion is carried out correctly, and the custom pulse is converted to a `pulse.Waveform` as it should. Fixed [#11828](https://github.com/Qiskit/qiskit/issues/11828).

* Fixed an issue in the [`InverseCancellation`](/api/qiskit/qiskit.transpiler.passes.InverseCancellation "qiskit.transpiler.passes.InverseCancellation") transpiler pass where in some cases it would incorrectly cancel a self-inverse parameterized gate even if the parameter value didn’t match. Fixed [#11815](https://github.com/Qiskit/qiskit/issues/11815).

* [`BasePassManager.run()`](/api/qiskit/qiskit.passmanager.BasePassManager#run "qiskit.passmanager.BasePassManager.run") will no longer leak the previous [`PropertySet`](/api/qiskit/qiskit.passmanager.PropertySet "qiskit.passmanager.PropertySet") into new workflows when called more than once. Previously, the same [`PropertySet`](/api/qiskit/qiskit.passmanager.PropertySet "qiskit.passmanager.PropertySet") as before would be used to initialize follow-on runs, which could mean that invalid property information was being given to tasks. The behavior now matches that of Qiskit 0.44. Fixed [#11784](https://github.com/Qiskit/qiskit/issues/11784).

* A bug has been fixed in `convert_durations_to_dt()` where the function assumed its inputs were all in seconds, rather than reading the actual unit. This could lead to wrong orders of magnitude in the reported circuit durations.

### Prelude

We are very pleased to release Qiskit 1.0.0. This release is the culmination of 7 years of development to mature Qiskit into a stable, high- performance SDK for quantum computing, and is the start of a new era for the Qiskit project and community. Besides general performance and stability improvements, the most significant changes with the 1.0.0 release relate to the stability policy, release cycles, and versioning. Qiskit is now formally using [semantic versioning](https://semver.org/), and this means that, for the entire lifecycle of the 1.x release series, the project is committed to maintaining backwards compatibility in its public documented APIs. We’re also now starting to offer bugfix support for major versions, so that you continue to have a supported branch for 6 months after the release of the next major version. This starts now with the 1.x and 0.x major series: the 0.46.x release will continue to be supported, with periodic patch releases that contain bug fixes, for 6 months after the release of 1.0. That is, 0.46.x will be supported until 2024-08. You can see the full details of the new policy here:

* The [`TemplateOptimization`](/api/qiskit/qiskit.transpiler.passes.TemplateOptimization "qiskit.transpiler.passes.TemplateOptimization") pass will now return parametric expressions using the native symbolic expression format of [`ParameterExpression`](/api/qiskit/qiskit.circuit.ParameterExpression "qiskit.circuit.ParameterExpression"), rather than always using Sympy. For most supported platforms, this means that the expressions will be Symengine objects. Previously, the pass could return mismatched objects, which could lead to later failures in parameter-handling code.

### Bug Fixes

* Update properties and configuration information of [`FakeOpenPulse2Q`](/api/qiskit/qiskit.providers.fake_provider.FakeOpenPulse2Q "qiskit.providers.fake_provider.FakeOpenPulse2Q") backend. Missing gate properties were added for some gates defined in the pulse defaults so that the gates defined in the two locations were consistent.

* [`InstructionDurations.from_backend()`](/api/qiskit/qiskit.transpiler.InstructionDurations#from_backend "qiskit.transpiler.InstructionDurations.from_backend") now returns an instance of any subclass of [`InstructionDurations`](/api/qiskit/qiskit.transpiler.InstructionDurations "qiskit.transpiler.InstructionDurations") instead of the base class.
