QECTOR: Advanced Quantum Error Correction Engineering
QECTOR is a sophisticated, high-performance environment designed for quantum error correction (QEC) focused on integration with Claude Code and Claude Desktop, compatible across Windows, macOS, and Linux platforms. This robust system is grounded in strong mathematical foundations, strictly enforcing the condition $H c \equiv s \pmod 2$ across 10 distinct code families supported by 5 different MWPM/BP-OSD backends. It provides a reliable infrastructure to maintain fail-closed integrity crucial for both enterprise and academic quantum research.

Key Features

• Local and Secure: QECTOR operates entirely offline, ensuring zero egress security. This design guarantees that sensitive quantum error correction simulations are never transmitted to the cloud, safeguarding proprietary information.
• Mathematical Verification: Every component of syndrome decoding is mathematically strict. Approximations are not tolerated, ensuring the utmost reliability in quantum state management.
• Fail-Safe Mechanisms: The system incorporates deterministic error notifications for mismatched matrix dimensions or unrecognized code families, eliminating silent failures that could corrupt quantum states.
• Statistical Precision: All Lattice Error Rate (LER) threshold sweeps are executed with exact Wilson 95% confidence intervals, rejecting any point estimates that lack bounds.

Comprehensive Ecosystem

QECTOR features a variety of commands, specialized agents, and domain primitives designed to cater to diverse aspects of quantum research and development:
