A tool for Quantum Circuit Mapping

MQT QMAP - A tool for Quantum Circuit Compilation

A tool for quantum circuit compilation developed as part of the Munich Quantum Toolkit (MQT)[^1] by the Chair for Design Automation at the Technical University of Munich. It builds upon our quantum functionality representation (QFR). .

Getting Started

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

(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())

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 and a minimum CMake version of 3.19. 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.
