Quantum Key Distribution and the Future of Encryption

Explore the future of encryption and quantum key distribution in this 27-minute Black Hat conference talk. Delve into the potential impact of quantum computing on information security over the next decade. Learn how multi-qubit systems using quantum algorithms could compromise even 4096-bit PK encryption in seconds, necessitating new quantum encryption methods. Examine real-world experiments in Quantum Key Distribution conducted by BT and partners, offering insights into the future landscape of encryption. Consider the implications of a world where all communications are vulnerable to quantum computer eavesdropping, and discover how new systems leveraging quantum mechanics may be the key to ensuring privacy. Cover topics such as Richard Feynman, quantum mechanics, wave-particle duality, decoherence, Einstein's entanglement, qubits, coherence, quantum algorithms, Grover's algorithm, lab experiments by Google and NSA, post-quantum encryption, and BT Toshiba's contributions to the field.
