Game-Theoretic Discovery of Quantum Error-Correcting Codes Through Nash Equilibria

The project represents a novel intersection between non-cooperative game theory and quantum information science. By recasting the search for Calderbank-Shor-Steane (CSS) codes as a strategic game, it moves away from traditional brute-force or purely algebraic methods toward a mechanistic search strategy. However, with 0 stars and minimal activity over 179 days, it currently exists as a theoretical research artifact rather than a functional tool or library. The defensibility is low because the implementation is a small-scale proof of concept (rediscovering the [[15,7,3]] code), which is a standard benchmark in the field. While the methodology is intellectually significant, it lacks a data or community moat. Frontier labs are unlikely to prioritize this specific niche of quantum code discovery in the short term, as they currently focus on large-scale hardware-software integration for existing topological codes (like Surface or Color codes). The displacement horizon is long because the practical application of these discovered codes depends on the maturation of fault-tolerant quantum hardware.
