This chapter highlights the transformation of secure communications through the incorporation of quantum mechanics. Over the past four decades, this groundbreaking theory has quietly revolutionized private communication. The chapter provides a concise historical overview of this field's inception, tracking the development of its pioneering protocol, BB84. It delves deeply into the protocol's evolution, spotlighting its milestones and challenges. Furthermore, it offers a panoramic view of the entire quantum key distribution landscape, encompassing continuous variable protocols designed to harness existing telecom technologies and device-independent quantum key distribution protocols aimed at achieving secure key exchange with minimal reliance on the experimental setup.

  1. Mesoscopic Quantum Communication via Photon-Number Moments

    quant-ph 2026-08 conditional novelty 6.0 of 10

    Eight-symbol quantum key distribution is simulated by encoding in photon-number moments and securing with twin-beam correlation-based detection of intercept-resend and beam-splitting attacks.

  2. Quantum Internet in a Nutshell -- Advancing Quantum Communication with Ion Traps

    quant-ph 2025-07 conditional novelty 6.0 of 10

    A trapped-ion quantum computer emulates BB84 and BBM92 with cloning and side-channel attacks, and simulated small QEC codes can suppress channel noise and fingerprint the noise channel.

  3. Universal Fluctuations in the Tail Probability for d=2 Random Walks in Space-Time Random Environments

    cond-mat.stat-mech 2025-08 reject novelty 4.0 of 10

    The reported d=2 random-walk universality result is unsupported: the full text is a quantum federated learning survey that never mentions random walks, tail probabilities, or lambda_ext.
