A framework for research and education for mixed-dimensional qudit quantum computing developed as part of the Munich Quantum Toolkit (MQT) by the Chair for Design Automation at the Technical University of Munich.

If you have any questions, feel free to create a discussion or an issue on GitHub.

mqt.qudits is available via PyPI for all major operating systems and supports Python 3.9 to 3.13.

(.venv) $ pip install mqt.qudits

The implementation is compatible with any C++17 compiler, a minimum CMake version of 3.19, and Python 3.9+.

Building (and running) is continuously tested under Linux, macOS, and Windows using the latest available system versions for GitHub Actions.

MQT Qudits has been developed based on methods proposed in the following papers:

• K. Mato, S. Hillmich and R. Wille, "Mixed-Dimensional Qudit State Preparation Using Edge-Weighted Decision Diagrams", Design Automation Conference (DAC), 2024.

• K. Mato, S. Hillmich and R. Wille, "Mixed-Dimensional Quantum Circuit Simulation with Decision Diagrams", International Conference on Quantum Computing and Engineering (QCE), 2023.

• K. Mato, S. Hillmich, R. Wille, "Compression of Qubit Circuits: Mapping to Mixed-Dimensional Quantum Systems", International Conference on Quantum Software (QSW), 2023.

• K. Mato, M. Ringbauer, S. Hillmich and R. Wille, "Compilation of Entangling Gates for High-Dimensional Quantum Systems", Asia and South Pacific Design Automation Conference (ASP-DAC), 2023.

• K. Mato, M. Ringbauer, S. Hillmich and R. Wille, "Adaptive Compilation of Multi-Level Quantum Operations", International Conference on Quantum Computing and Engineering (QCE), 2022.

MQT Qudits is the result of the project NeQST funded by the European Union under Horizon Europe Programme - Grant Agreement 101080086.
