This project represents fundamental research at the intersection of condensed matter physics and quantum information science. The defensibility is high (8) not because of a software moat, but because of the extreme 'deep tech' barrier to entry; replicating these results requires multi-million dollar dilution refrigerators, nanofabrication facilities, and PhD-level expertise in Andreev bound states. The quantitative signal of 18 forks against 0 stars is a classic signature of a high-value academic release: it indicates that other research laboratories (the 'competitors' in this niche) are actively cloning the repository to verify results or adapt the simulation code for their own experimental setups. While Frontier labs like OpenAI or Anthropic have zero interest here, the 'Frontier' in quantum hardware (Microsoft Station Q, Google Quantum AI, and QuTech) are the primary entities that would either absorb this research or compete with it. Microsoft, in particular, has bet heavily on topological qubits (Majoranas), making this highly relevant to their roadmap. The platform domination risk is high because if these protocols prove essential for scaling Kitaev chains, the intellectual property will likely be consolidated by one of the few giants capable of building a full-stack quantum computer. Displacement is unlikely in the short term (3+ years) as the hardware realization of these theoretical models remains one of the hardest problems in physics.

The reusable building blocks distilled from this project — each a mechanism you could lift into your own.
PhaseDependentSupercurrent -> ParityState
Detect the parity of an Andreev molecule by measuring its phase-dependent supercurrent profile.
ControlParameters<Phase,GateVoltage> -> ParityState
Control the parity state of a multi-quantum-dot Josephson junction via non-local phase and gate voltage tuning.
