Modeling of simple bandpass filters: bandwidth broadening of Josephson parametric devices due to non-Markovian coupling to dressed transmission-line modes

The project is a theoretical physics framework rather than a software product, evidenced by its 3-day age and 0 stars. While the 4 forks indicate immediate interest from the academic community (likely the authors' peers), it lacks a commercial or software moat. Its defensibility is rooted in deep domain expertise in superconducting quantum circuits, which is highly specialized but easily reproducible by other research groups (Yale, ETH Zurich, Delft) once the paper is published. Frontier AI labs like OpenAI or Anthropic have no interest in low-level microwave circuit engineering, though quantum hardware giants like IBM or Google Quantum AI may find the findings relevant for their JPA readout chains. The primary risk is not platform domination, but obsolescence through superior theoretical models or alternative hardware architectures (e.g., traveling wave parametric amplifiers) that solve the bandwidth issue differently.
