Qhronology: A Python package for studying quantum models of closed timelike curves

Qhronology is a highly specialized academic tool designed as a reference implementation for a theoretical physics paper. With 0 stars and a 3-day history, it currently functions as a personal research experiment rather than a production-grade library. Its defensibility is low (score 2) because the software itself is easily reproducible by researchers in the same niche; the value lies entirely in the underlying mathematical models (Deutschian CTCs or Post-Selected CTCs) which are public domain in physics. Frontier labs (OpenAI, Google) have no incentive to compete in the 'quantum time travel simulation' space as it lacks commercial application or relevance to current AGI/LLM scaling. However, for its specific niche, it could become a standard if it gains adoption within the quantum information theory community. The lack of stars/velocity suggests it has not yet transitioned from a paper accompaniment to a community-driven project. Its primary competition would be general-purpose quantum simulators like IBM's Qiskit or Google's Cirq, which could theoretically implement CTC logic as a plugin, but the specific focus on 'temporal paradox resolution' gives it a unique but narrow academic moat.
