QECTOR Decoder Workbench v3.5.0

Production Release

Quantum Error Correction Analysis Suite with CustomTkinter GUI, 29-tool MCP server, and multi-format documentation export.

Quick Start (from source)

pip install -r requirements.txt
python main.py

Download v3.5.0

• QectorWorkbenchSetup.exe — Windows installer (64-bit, Inno Setup)
• QectorWorkbench-v3.5.0-production.zip — Complete production bundle including standalone EXE, docs, and SHA256 manifest

Key Features

6 GUI Tabs

• Code Explorer — Build codes from 6 families (repetition, ring, rotated_surface, unrotated_surface, toric, heavy_hex) with configurable distance. View code properties (qubits, checks, distance, rate).
• Decoder Lab — Interactive single-syndrome decoding with 5 decoders (union_find, fast_union_find, blossom, sparse_blossom, bp_osd). Configurable error rate and seed.
• Benchmark Suite — Configurable decode benchmarks with throughput and latency stats (mean/p50/p99/min/max). Export results to JSON.
• Batch & Streaming — Batch decode with explicit CPU/CUDA/OpenCL routing (no silent fallback — unavailable backends fail loudly). Streaming decode with sliding-window commit semantics.
• Hardware & System — Auto-detect CUDA, OpenCL, and CPU backends via qector_decoder_v3 APIs (cuda_is_available, opencl_is_available). System info and hardware-aware decoder recommendations via hardware_routing.detect_hardware() and hardware_routing.recommend().
• Documentation Studio — Multi-format doc export: Markdown, JSON, HTML, LaTeX, PDF (matplotlib PdfPages), SVG (matplotlib). Full provenance metadata and decoder recommendation tables.

29-Tool MCP Server

• Real stdio JSON-RPC 2.0 transport (protocol version 2024-11-05)
• stdin/stdout newline-delimited JSON-RPC — no HTTP bridge, no port 8765
• Implements initialize, notifications/initialized, ping, tools/list, tools/call
• All 29 tools wired to the real backend.py API

Backend

• Thin Python wrapper over qector_decoder_v3 (Rust core + Python bindings)
• 6 code families × 5 decoders, all cross-compatible
• Batch decode: CPU/CUDA/OpenCL via CPUBatchDecoder/CUDABatchDecoder/OpenCLBatchDecoder
• Streaming decode: sliding-window FIFO with configurable window size, committed corrections, logical error rate tracking
• Spring-layout Tanner graph computation for all families

Other

• Auto-updater checking PyPI for newer qector_decoder_v3 on boot
• PyInstaller EXE packaging with Inno Setup installer
• Fonts: Consolas (mono), Segoe UI (body/heading)

Requirements

• Python >=3.11
• qector-decoder-v3 >=0.6.2
• customtkinter >=5.2.0
• numpy, scipy, Pillow, matplotlib, psutil
