⚛Clifford simulationNoise-free stabilizer simulation on the CHP / Aaronson-Gottesman tableau, with a stim-style uppercase gate API (H, S, CX, CZ, M, R, ...).
🌀General noise, cheaplyPauli, coherent and amplitude-damping channels via importance-sampled stabilizer trajectories with stratified variance reduction (arXiv:2512.07304).
🛡Decoder-ready QECDetectors, observables, detector error models and ready-made repetition / rotated surface codes. Feed MWPM, BP or ML decoders directly; none bundled.
🚀Native core, Python surfaceThe tableau is a Rust crate exposed through PyO3: the hot path is compiled, every extension seam stays Pythonic.
