MQT QMAP - A tool for Quantum Circuit Compilation

A tool for quantum circuit compilation developed as part of the Munich Quantum Toolkit (MQT) by the Chair for Design Automation at the Technical University of Munich. It builds upon MQT Core, which forms the backbone of the MQT.

If you have any questions, feel free to contact us via quantum.cda@xcit.tum.de or by creating an issue on GitHub.

Getting Started

QMAP is available via PyPI for Linux, macOS, and Windows and supports Python 3.9 to 3.13.

(venv) $ pip install mqt.qmap

Compiling a given quantum circuit to a certain device is as easy as

from mqt import qmap
from qiskit import QuantumCircuit
from qiskit.providers.fake_provider import FakeLondon

circ = QuantumCircuit(3)
circ.h(0)
circ.cx(0, 1)
circ.cx(0, 2)

circ_mapped, results = qmap.compile(circ, arch=FakeLondon())

Optimizing a Clifford circuit is as easy as

from mqt import qmap
from qiskit import QuantumCircuit

circ = QuantumCircuit(2)
circ.h(1)
circ.cx(0, 1)
circ.h(0)
circ.h(1)

circ_opt, results = qmap.optimize_clifford(circ)

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

System Requirements and Building

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