Quantum-Secure-By-Construction (QSC): A Paradigm Shift For Post-Quantum Agentic Intelligence

This is an early-stage academic paper (25 days old) introducing a conceptual paradigm rather than a deployed system. Zero stars, forks, and velocity indicate no community traction or working implementation available. The core contribution—framing quantum-secure communication as an architectural first-class concern for agentic AI rather than a bolt-on property—is a reasonable novel combination of known PQC techniques with system design principles, but it lacks: (1) reference implementation, (2) empirical validation, (3) user adoption, (4) competitive positioning against existing PQC tooling. Defensibility is extremely low because: the work is pre-prototype stage; post-quantum cryptography libraries (liboqs, pqcrypto, etc.) already exist and are commodity; the novelty is in *how to architect* systems, not in new crypto primitives; frontier labs (OpenAI, Anthropic, Google) are actively designing secure agentic systems and are well-positioned to integrate PQC natively. High frontier risk because this describes a fundamental design pattern that becomes more valuable as agentic AI scales—exactly the domain where frontier labs operate and can dictate standards. A frontier lab could internalize this paradigm as a design guide within 1-2 quarters without external tooling. The paper may influence thinking but will not defensibly position an independent project unless a strong reference implementation with operational credentials emerges within 6 months.
