Quantum Communication – Historical Foundation

Quantum Communication – Historical Foundation The roots of quantum communication lie in exploiting physics—not math—for secure information transfer. Quantum communication began as a theoretical pursuit in the 1980s when Bennett and Brassard introduced the BB84 protocol for secure key exchange using quantum bits. Unlike classical encryption, which depends on hard-to-solve math problems, quantum key distribution (QKD) is secure because measurement disturbs the quantum state, revealing eavesdropping. This fundamental law created a new paradigm for security. Throughout the 1990s and early 2000s, experiments validated QKD with entangled photons over short distances, laying the groundwork for future networks. Born from theory and experimentation, quantum communication represents a shift in how we understand and implement information security.
