Why Quantum Computing Requires Quantum Cryptography

The video discusses the concept of a quantum internet, emphasizing the need for quantum cryptography due to the advent of quantum computing. It explains how quantum key distribution (QKD) can secure communications against eavesdropping and man-in-the-middle attacks. The BB84 protocol and Eckert's entanglement-based protocol are detailed as methods for secure key generation. The video concludes with a discussion on the challenges of building a quantum internet and its potential future impact.
