Experiments with the Toric code: Circuit-level noise simulations and Equivariant Neural Decoder implementation.

A Python simulation toolkit for toric-code decoding with minimum-weight perfect matching under perfect and noisy syndrome measurements.

Biased Pauli noise (weighted matching) and heralded erasure (from-scratch peeling decoder) on the toric code: reproducing the 0.5 erasure threshold and contrasting noise profiles.

Simulation study of how many stabiliser measurements and syndrome-extraction CNOTs erasure recovery needs when only checks touching erased qubits are measured, on toric and bivariate bicycle codes (n=32-144), with noisy-readout sweep.

Simulation study: how much does imperfect erasure-flag efficiency cost matching decoding of the toric code, does recalibrating the unflagged prior help, and how does a flag-aware neural decoder compare? L=3-7, 3 seeds.
