| contents | Quantum Key Distribution (QKD) stands as a revolutionary approach to secure communication, using the principles of quantum mechanics to establish unbreakable channels. Unlike traditional cryptography, which relies on the computational difficulty of mathematical problems, QKD utilizes the inherent properties of quantum states to achieve information-theoretic security. This means that the security of the key exchange is guaranteed by the laws of physics, making it theoretically unbreakable even by an adversary with unlimited computational power. Currently, one of the most viable ways to implement QKD for communication is via photonics, namely, using phase-preserving long-distance optical fibers. The objective of this project is to implement photonic QKD in a laboratory setting. This will help demonstrate the protocol's robustness and provide a feasible implementation for educational demonstrations. |
