TLDR
Practical application of the generalized Bells theorem in the so-called key distribution process in cryptography is reported, based on the Bohms version of the Einstein-Podolsky-Rosen gedanken experiment andBells theorem is used to test for eavesdropping.
Abstract
Practical application of the generalized Bells theorem in the so-called key distribution process in cryptography is reported. The proposed scheme is based on the Bohms version of the Einstein-Podolsky-Rosen gedanken experiment and Bells theorem is used to test for eavesdropping. © 1991 The American Physical Society.

No signaling and quantum key distribution.

TL;DR: A key distribution scheme provably secure against general attacks by a postquantum eavesdropper limited only by the impossibility of superluminal signaling is described, which stems from violation of a Bell inequality.

Quantum entanglement for secret sharing and secret splitting

TL;DR: In this article, a two-particle quantum entanglement protocol for secret sharing and splitting was proposed. But the secrecy sharing protocol must be carefully designed in order to detect eavesdropping or a dishonest participant.

Unconditional security in quantum cryptography

TL;DR: In this article, basic techniques to prove the unconditional security of quantum crypto graphy are applied to a quantum key distribution protocol proposed by Bennett and Brassard [1984] and considered a practical variation on the protocol in which the channel is noisy and photos may be lost during the transmission.

Quantum resource theories

TL;DR: This paper introduced a new development in theoretical quantum physics, the ''resource-theoretic'' point of view, which aims to be closely linked to experiment, and to state exactly what result you can hope to achieve for what expenditure of effort in the laboratory.

Quantum Computing

TL;DR: The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics as mentioned in this paper, and this review aims to summarise not just quantum computing, but the whole subject of Quantum Information Theory.
