Journal ArticleDOI
Physical one-way functions
TL;DR: The concept of fabrication complexity is introduced as a way of quantifying the difficulty of materially cloning physical systems with arbitrary internal states as primitives for physical analogs of cryptosystems.

TL;DR: In this article, the authors review recent progress in OAM beam generation/detection, multiplexing/demultiplexing, and its potential applications in different scenarios including free-space optical communications, fiber-optic communications, and RF communications.
Book ChapterDOI
Experimental quantum cryptography
TL;DR: Initial results from an apparatus and protocol designed to implement quantum public key distribution are described, by which two users exchange a random quantum transmission, consisting of very faint flashes of polarized light, which remains secure against an adversary with unlimited computing power.

TL;DR: This work reports the development and launch of a low-Earth-orbit satellite for implementing decoy-state QKD—a form ofQKD that uses weak coherent pulses at high channel loss and is secure because photon-number-splitting eavesdropping can be detected.
Journal ArticleDOI
Fundamental limits of repeaterless quantum communications.
TL;DR: The fundamental rate-loss tradeoff affecting any protocol of quantum key distribution is determined, which sets the limits of point-to-point quantum communications and provides precise and general benchmarks for quantum repeaters.
