Understanding Quantum Security Basics

Quantum security is fundamentally rooted in the principles of quantum mechanics, particularly through secure quantum key distribution (QKD) systems. QKD enables two parties to generate a shared secret key with provable security against eavesdropping. A significant advancement in this field involves the on-demand generation of single photons from solid-state quantum emitters, such as defects in hexagonal boron nitride (hBN). The successful implementation of protocols like B92 and BB84 demonstrates how these single-photon sources can achieve sifted key rates and maintain low error rates, crucial for reliable communication.
