MQT Bench - A MQT tool for Benchmarking Quantum Software Tools

MQT Bench - Benchmarking Software and Design Automation Tools for Quantum Computing

MQT Bench is a quantum circuit benchmark suite with cross-level support, i.e., providing the same benchmark algorithms for different abstraction levels throughout the quantum computing software stack. MQT Bench is hosted at https://www.cda.cit.tum.de/mqtbench/. It is part of the Munich Quantum Toolkit (MQT).

Key Features

• Comprehensive Quantum Benchmark Suite: Provides a wide range of quantum circuit benchmarks, including algorithms such as GHZ, QAOA, QFT, Grover, Shor, and many more. List of benchmarks
• Cross-Level Benchmark Generation: Supports four abstraction levels—algorithmic, target-independent, target-dependent native gates, and target-dependent mapped—enabling benchmarking across the entire quantum software stack. Abstraction levels
• Flexible Target and Gateset Support: Generate circuits for various hardware targets and native gatesets, including IBM, IonQ, Quantinuum, Rigetti, and more. Supported devices and gatesets
• Python API, CLI, and Web Interface: Use MQT Bench programmatically via Python, from the command line, or through an interactive web interface—whichever fits your workflow. Usage guide
• Parameterized and Mirror Circuits: Easily generate parameterized circuits (with random or symbolic parameters) and mirror circuits for robust benchmarking and error detection. Quickstart
• Export to Standard Formats: Save generated circuits in OpenQASM 2, OpenQASM 3, and QPY formats for compatibility with other quantum tools. Output formats
• Extensible and Open Source: Actively maintained, fully open-source, and designed for easy integration and extension within the quantum computing community.

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 the Munich Quantum Software Company (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 Bench a reality!

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.bench is available via PyPI.

(.venv) $ pip install mqt.bench

The following code gives an example on the usage:

from mqt.bench import BenchmarkLevel, get_benchmark

# Get a benchmark circuit on algorithmic level representing the GHZ state with 5 qubits
qc_algorithmic_level = get_benchmark(
    benchmark="ghz", level=BenchmarkLevel.ALG, circuit_size=5
)

# Draw the circuit
print(qc_algorithmic_level.draw())

[!NOTE] MQT Bench is also available as a PennyLane dataset.

Detailed documentation and examples are available at ReadTheDocs.

System Requirements

MQT Bench can be installed on all major operating systems with all officially supported Python versions. Building (and running) is continuously tested under Linux, macOS, and Windows using the latest available system versions for GitHub Actions.
