Quantum Encryption Explained Simply (2026) Quantum Encryption Explained Simply (2026) Quantum encryption in 2026 mainly refers to quantum key distribution (QKD) , a method that uses the physics of entanglement or single photons to create shared secret keys with information-theoretic security. Unlike purely mathematical defenses, QKD detects eavesdropping by changes in quantum states, making interception visible. In practice, quantum encryption complements post-quantum cryptography (PQC) rather than replacing it: PQC protects data-at-rest and application layers, while QKD hardens key exchange for links where “harvest-now, decrypt-later” risk is high. If you’re new to the stack, start with our overviews of Quantum Computing (2026) and How Quantum Computers Work (2026) . 1) What is “quantum encryption” in simple terms?
