Welcome to DDSIM’s documentation!

A tool for quantum circuit simulation by the Chair for Design Automation at the Technical University of Munich. DDSIM is part of the Munich Quantum Toolkit (MQT; formerly known as JKQ and developed by the Institute for Integrated Circuits at the Johannes Kepler University Linz). It builds upon our quantum functionality representation (QFR) and our decision diagram (DD) package.

The tool builds upon our quantum functionality representation (QFR) which in turns builds on our decision diagram (DD) package.
