Dependencies

This project relies on several third-party libraries and tools. Below is a comprehensive list of these dependencies along with their purposes, versions, and licenses.

Core Runtime Dependencies

These dependencies are linked into the shared library and shipped with every built wheel or binary.

Dependency	Version	License	Purpose
QDMI	1.3.2	Apache-2.0 with LLVM-exception	QDMI specification and interface headers
nlohmann/json	3.12.0	MIT License	JSON parsing and serialization
CPR	1.14.2	MIT License	C++ Requests HTTP client library for backend communication

Note

In pre-built wheels, libcurl and its transitive dependencies (OpenSSL, nghttp2, etc.) are automatically bundled by platform-specific repair tools: auditwheel on Linux, delocate on macOS, and delvewheel on Windows. On Linux, the exact bundled versions correspond to those available in the manylinux_2_28 container images used by cibuildwheel.

Build Dependencies

Used to build the Python package and bridge packaging with the CMake-based native build. These are not shipped in any binary or wheel.

Dependency	Version	License	Purpose
scikit-build-core	≥1.0.1	Apache-2.0	Python build backend and CMake integration

Optional Python Integration Dependencies

These are installed when users request the qiskit extra via iqm-qdmi[qiskit]. They live in the user’s Python environment and are not bundled inside the wheel itself.

Dependency	Version	License	Purpose
MQT Core	~=3.7.0	MIT License	QDMI-aware Qiskit provider, backend, sampler, and estimator integrations
Qiskit	≥1.1	Apache-2.0	Quantum circuit construction, transpilation, and primitive interfaces

End-to-End Example Dependencies

On top of the Python integration dependencies, the example scripts rely on additional libraries to construct and execute their workloads. The scripts in examples/ declare these dependencies in their own PEP 723 metadata. These dependencies are resolved when the scripts are executed locally and are not shipped as part of the iqm-qdmi wheel.

Dependency	Version	License	Applies to	Purpose
MQT Bench	≥2.2.2	MIT License	Benchmark examples	Standardized benchmark circuit generation
Qiskit Nature	≥0.7.2	Apache-2.0	QSCI example	Electronic-structure modeling and qubit mapping

Test Dependencies

Used for testing only, not shipped in any binary or wheel.

C++ Tests

Dependency	Version	License	Purpose
googletest	1.17.0	BSD-3-Clause	C++ unit and integration testing

Python Tests

Dependency	Version	License	Purpose
pytest	≥9.0.1	MIT License	Testing framework
pytest-console-scripts	≥1.4.1	MIT License	Testing CLI entry points
pytest-cov	≥7.0.0	MIT License	Test coverage reporting
pytest-sugar	≥1.1.1	BSD-3-Clause	Prettier test output formatting
pytest-xdist	≥3.8.0	MIT License	Parallel test execution

Documentation Dependencies

Used to generate the documentation site and API reference, not shipped in any binary or wheel.

Dependency	Version	License	Purpose
Doxygen	1.16.1	GNU GPL v2	API documentation generation
Sphinx	≥8.1.3	BSD-2-Clause	Documentation site generator
MyST-NB	≥1.3.0	BSD-3-Clause	Markdown and notebook pages
Breathe	≥4.36.0	BSD License	Doxygen XML to Sphinx bridge
Sphinx AutoAPI	≥3.6.1	MIT License	Python API reference pages
Furo	≥2025.9.25	MIT License	Sphinx HTML theme
Sphinx Copybutton	≥0.5.2	MIT License	Copy-to-clipboard buttons for code blocks
Sphinx Design	≥0.6.1	MIT License	Layout and UI directives such as cards, grids, and tabs

Note

Doxygen is licensed under GNU GPL v2, but documents produced by Doxygen are derivative works of the input, not of Doxygen itself, and are therefore not affected by the GPL. The generated documentation remains under the project’s own license terms.

Development Dependencies

Used for local development workflows, not shipped in any binary or wheel.

Dependency	Version	License	Purpose
nox	≥2026.4.10	Apache-2.0	Session runner for tests, linting, docs, packaging, and examples
