Stim: Quantum Stabilizer Circuits

Stim is a fast Python library for high-performance simulation and analysis of quantum stabilizer circuits, particularly those used in quantum error correction (QEC). It focuses on providing low-level, fast building blocks for simulating circuits with thousands of qubits and millions of operations, enabling rapid Monte Carlo sampling. The library maintains a regular release cadence, with minor versions typically released every few months, ensuring active development and improvements.
