Qutility Frontier
Qutility Frontier is an open-source Python package for implementing scalable and hardware-agnostic quantum benchmarking protocols. The package provides implementations of recently proposed scalable benchmarks and offers tools to generate benchmark instances in a reproducible form. The Clifford Volume Benchmark implemented in this package is part of the EU Quantum Flagship KPIs for quantum computer benchmarking.
Key features
- Open-source Python package designed to simplify the implementation of platform-independent quantum benchmark protocols.
- A benchmark base class with a well-defined workflow, including customizable methods.
- A lightweight Python-based representation of quantum circuits, enabling intuitive and flexible implementation of benchmark logic while remaining independent of any specific SDK.
- Hardware-agnostic circuit export via OpenQASM (QASM 2 / QASM 3), with optional SDK-specific adaptations (e.g., gate aliasing).
- A JSON schema to store complete benchmark instances.
Implemented Scalable Benchmarks
- Clifford Volume Benchmark. Efficiently verifiable using stabilizer techniques. Measures stabilizer and destabilizer observables to quantify device performance.
- Free-Fermion Volume Benchmark. Based on Gaussian / free-fermionic circuits (SO(2n) transformations). Evaluates device performance through Majorana-mode based observables.
