This repository contains a research paper exploring to what extent existing encryption methods may become obsolete in the presence of Quantum Key Distribution (QKD).
The paper examines:
- How current encryption systems protect data in practice
- The mathematical foundations of RSA and Elliptic Curve Cryptography
- Quantum computing principles such as superposition, entanglement, and interference
- QKD protocols including BB84, CV-QKD, and E91
- The role of Post-Quantum Cryptography (PQC) in securing classical channels
- Practical limitations of deploying quantum communication systems
Conclusion: QKD is unlikely to replace classical encryption on its own, because it still depends on a secure classical communication channel. However, when combined with Post-Quantum Cryptography, it points toward a transition away from current classical algorithms and toward more quantum-resilient security architectures.
