MQT ProblemSolver provides a framework to utilize quantum computing as a technology for users with little to no quantum computing knowledge It is developed as part of the Munich Quantum Toolkit (MQT).
- Progress toward an automated framework for solving optimization and constraint satisfaction problems with minimal quantum expertise
- Hybrid classical–quantum approaches for domain-specific applications such as satellite mission planning
- Methods for reducing compilation time through pre-compilation and optimizing quantum circuits
- Equivalence checking of classical circuits with quantum computing
- Utilizing resource estimation for evaluating and optimizing hardware requirements regarding fault-tolerant quantum computing
If you have any questions, feel free to create a discussion or an issue on GitHub.
The Munich Quantum Toolkit (MQT) is developed by the Chair for Design Automation at the Technical University of Munich and supported by the Munich Quantum Software Company (MQSC). Among others, it is part of the Munich Quantum Software Stack (MQSS) ecosystem, which is being developed as part of the Munich Quantum Valley (MQV) initiative.
Thank you to all the contributors who have helped make MQT ProblemSolver a reality!
The MQT will remain free, open-source, and permissively licensed—now and in the future. We are firmly committed to keeping it open and actively maintained for the quantum computing community.
