Short Description
Stim circuits from “New circuits and an open source decoder for the color code” (Gidney & Jones, 2023), consolidated into a single Parquet artifact for Aqora.
Background
The paper introduces two stabilizer-measurement schedules for color-code quantum error correction:
- Superdense circuits multiplex stabilizer measurements via Bell pairs.
- Middle-out circuits fold stabilizers without ancillas, achieving the best logical-error performance reported to date.
Both constructions are benchmarked under circuit-level noise and outperform earlier color-code circuits. The authors also release Chromobius, an open-source Möbius decoder that operates at roughly 300k decoding events per second across diverse noise models and circuit families. This dataset contains every Stim circuit, detector-error model, and simulation configuration used to generate the paper’s figures.
Contents
- Rows: 602 circuits (16 matchable minimum-weight cases + 586 unmatchable)
- Families: surface/toric color codes, phenom, midout, superdense, transit, pyramid, repetition, and related variants
- Metadata: parameters parsed from filenames (rounds
r, distance d, noise model/probability, qubit count q, optional layout dimensions w/h)
- Payload: full Stim source code for each circuit
