MQT DDSIM - A quantum circuit simulator based on decision diagrams written in C++

A tool for classical quantum circuit simulation developed as part of the Munich Quantum Toolkit (MQT). It builds upon MQT Core, which forms the backbone of the MQT.

Contributors and Supporters

The Munich Quantum Toolkit (MQT) is developed by the Chair for Design Automation at the Technical University of Munich and supported by MQSC. Among others, it is part of the Munich Quantum Software Stack (MQSS) ecosystem, which is being developed as part of the Munich Quantum Valley (MQV) initiative.

Thank you to all the contributors who have helped make MQT DDSIM a reality!

Contributors to munich-quantum-toolkit/ddsim

The MQT will remain free, open-source, and permissively licensed—now and in the future. We are firmly committed to keeping it open and actively maintained for the quantum computing community.

Getting Started

MQT DDSIM bundled with the provider and backends for Qiskit is available via PyPI.

uv pip install mqt.ddsim

The following code gives an example on the usage:

from qiskit import QuantumCircuit
from mqt import ddsim

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

print(circ.draw(fold=-1))

backend = ddsim.DDSIMProvider().get_backend("qasm_simulator")

job = backend.run(circ, shots=10000)
counts = job.result().get_counts(circ)
print(counts)

Detailed documentation and examples are available at ReadTheDocs.

System Requirements and Building

Building the project requires a C++ compiler with support for C++20 and CMake 3.28 or newer. For details on how to build the project, please refer to the documentation. Building (and running) is continuously tested under Linux, macOS, and Windows using the latest available system versions for GitHub Actions. MQT DDSIM is compatible with all officially supported Python versions.
