Quantum Cryptography: Principles, Protocols, and Practicalities


Listen Later

The provided text offers a comprehensive overview of quantum cryptography, detailing its foundational principles and practical applications in securing digital communications. It distinguishes between Post-Quantum Cryptography (PQC), which uses classical algorithms resistant to quantum attacks, and Quantum Cryptography (QC), exemplified by Quantum Key Distribution (QKD), which leverages quantum mechanics for secure key exchange. The document explores key QKD protocols like BB84 and E91, discusses the essential hardware components and network architectures involved, and provides a critical analysis of the technology's limitations, including those highlighted by the NSA. Finally, it outlines the ongoing standardization efforts for both PQC and QKD and envisions a future where quantum technologies are integrated into a secure, hybrid cryptographic landscape.
