Qector: Bringing a 15-back end Rust quantum decoder to Claude Desktop

QECTOR, a quantum error correction decoding environment built on the qector-decoder-v3 core, has released an official integration for Claude Code and Claude Desktop, enabling fully offline, zero-egress quantum error correction research and engineering. The plugin includes 13 slash commands, 5 specialized agent personas, 28 domain skills, and two local MCP servers (qector-library with 8 tools and qector-bench with 29 tools), with strict mathematical verification and fail-closed design. The integration is available via GitHub and supports Windows, macOS, and Linux, requiring Python 3.10+ and qector-decoder-v3==1.0.0.

Professional Claude Code & Claude Desktop Integration QECTOR is a high-performance, strictly verified quantum error correction engineering and research environment built for qector-decoder-v3 . By mathematically enforcing This repository provides the official integration for Claude Code and Claude Desktop Windows/macOS/Linux , completely offline with zero-egress security. 1.

Commands 13 Slash Commands - /qec-desktop-connector : Zero-friction Claude Desktop MCP configuration. - /qec-setup : Guided first-time setup and diagnostic audit. - /qec-facts : Quick reference for codes, decoders, and strict-math rules. - /qec-theorem : Formulations and proof obligations for Theorems 1-16. - /qec-reproduce : Reference manual Appendix D reproduction workflows. - /qec-decode : Single-shot syndrome decoding asserting parity. - /qec-threshold-sweep : LER sweeps with exact Wilson 95% confidence intervals. - /qec-wilson : Wilson 95% score interval calculator. - /qec-dem : Detector Error Models DEM and Stim circuit inspection. - /qec-code-inspect : Verify code parameters$ n,k,d $ and check matrices. - /qec-benchmark : Decoder latency and throughput microbenchmarks. - /qec-sinter : Sinter task templates and benchmark configuration. - /qec-validate-mcp : Validate tool schemas, JSON-RPC transport, and health. Agents 5 Specialized Personas qec-researcher : Academic research, paper reproduction, threshold sweeps. qec-developer : Code integration, API design, performance tuning. qec-validator : Formal verification, mathematical proof checking. qec-sysadmin : Operations, zero-egress monitoring, incident response. qec-hardware-engineer : Physical qubit characterization, cryogenic constraints. Skills 28 Domain Primitives Comprehensive instruction sets covering qector-core , qector-architecture , qector-bp-osd , qector-codes-builder , qector-math-foundations , qector-orchestration , qector-sinter , qector-dem-pipeline , and more. - Mathematical Strictness : Every single syndrome decoding must verify$H c \equiv s \pmod 2$ . Approximations are rejected. - Zero-Egress Security : Operations run 100% locally. The plugin never transmits QEC simulation telemetry to the cloud, protecting proprietary hardware IP. - Fail-Closed Design : Mismatched matrix dimensions, unrecognized code families, or invalid distance requests immediately raise deterministic errors rather than silently corrupting the quantum state. - Statistical Rigor : All LER threshold sweeps include exact Wilson 95% binomial score intervals. Point estimates without bounds are rejected. Requirements : Python 3.10+, qector-decoder-v3==1.0.0 , mcp==1.2.0 , numpy .
