Secure Quantum Communication: Simulation and Analysis of Quantum Key Distribution Protocols

This project is a standard pedagogical implementation of foundational Quantum Key Distribution (QKD) protocols. BB84, B92, and E91 are the 'Hello World' examples of quantum cryptography, and high-quality tutorials for implementing them in Qiskit are provided directly by IBM and various academic textbooks. The quantitative signals (0 stars and 5 forks at 31 days old) strongly suggest this is a classroom project or a student's thesis repository rather than a novel research contribution or a production-grade tool. There is no technical moat; the 'realistic quantum channel effects' mentioned are standard features of Qiskit's Aer simulator (NoiseModel). While frontier labs like OpenAI or Anthropic are unlikely to compete here, the project is already 'displaced' by more comprehensive and better-maintained libraries like QuTiP or IBM's own extensive Qiskit documentation. The defensibility is minimal as the logic is purely algorithmic based on well-documented 40-year-old protocols.
