MQT QCEC - A tool for Quantum Circuit Equivalence Checking

MQT QCEC - A tool for Quantum Circuit Equivalence Checking

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

Detailed documentation on all available methods, options, and input formats is available at ReadTheDocs.

If you have any questions, feel free to contact us via [e-mail] or by creating an issue on GitHub.

Getting Started

QCEC is available via PyPI for Linux, macOS, and Windows.

(venv) $ pip install mqt.qcec

The following code gives an example on the usage:

from mqt import qcec

# initialize the equivalence checker
ecm = qcec.EquivalenceCheckingManager("circ1.qasm", "circ2.qasm")

# execute the check
ecm.run()

# obtain the result
print(ecm.equivalence())

System Requirements and Building

The implementation is compatible with any C++17 compiler and a minimum CMake version of 3.14. Please refer to the documentation on how to build the project.

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