Quantum Key Distribution (QKD) represents a fundamental shift in secure communications. Unlike traditional encryption methods that rely on complex mathematics, QKD uses the principles of quantum mechanics—particularly entanglement and the no-cloning theorem—to generate and share secret keys between parties with absolute security. This session explores how QKD works, why it’s considered unbreakable by classical or quantum computers, and what its adoption means for the future of cryptography and data protection.
