Search-based decoder for quantum error correction (QEC) written in C++ and Python.
A library for analyzing Quantum Error Correction Codes from their Tanner Graphs.
A class that is able to develop any (n, k) linear code. Includes an implementation of an ASCII correcting linear code along with a simulation of error correction.
A Julia interface to popular python packages for decoding quantum error correcting codes.
Rotated planar surface code syndrome decoder detecting bit-flip (X) and phase-flip (Z) errors using parity-check stabilizer measurements.
Rotated planar surface code syndrome decoder detecting bit-flip (X) and phase-flip (Z) errors using parity-check stabilizer measurements.

Browser-based code-based cryptanalysis demo — Hint-ISD, eprint 2026/341. Decode a real syndrome with information-set decoding, feed it leaked hints one at a time, then watch the work factor fall from exponential toward polynomial. Real GF(2) arithmetic. No backend.
SAT-based solvers and instance generators for Syndrome Decoding (SDP) and Low-Weight Codeword (LWCP) problems.
Browser-based demo of multi-instance security degradation in code-based KEMs — BIKE, HQC, and Classic McEliece eroding below NIST Level 1 as one public key is reused across many session keys. Computes effective bit-security from published parameters and the DOOM syndrome-decoding formulas of ePrint 2026/517. No attack simulation. No backends.
A novel experimental framework for P vs NP using Absolute Metaphysical Solipsism: exact syndrome-support theorems, puncture fusion, observer-centered compression, proof certificates, algorithms, obstructions, and reproducible research.
