MQT YAQS—A Tool for Simulating Open Quantum Systems, Noisy Quantum Circuits, and Realistic Quantum Hardware

YAQS (pronounced “yaks” like the animals) is a Python library, primarily focused on simulating open quantum systems, noisy quantum circuits, and designing realistic quantum hardware.

YAQS is part of the Munich Quantum Toolkit (MQT) developed by the Chair for Design Automation at the Technical University of Munich.

This documentation provides a comprehensive guide to the MQT YAQS library, including installation instructions, notebook-like examples, and detailed API documentation. The source code of MQT YAQS is publicly available on GitHub at cda-tum/mqt-yaqs, while pre-built binaries are available via PyPI for all major operating systems and all modern Python versions.
