Quantum cryptography based on Bell's theorem.
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.read more

Large pulse attack as a method of conventional optical eavesdropping in quantum cryptography
TL;DR: It is concluded that additional protection is necessary for currently implemented quantum key distribution systems against the large pulse attack, a new strategy of eavesdropping on quantum cryptosystems, which eliminates the need of immediate interaction with transmitted quantum states.

The Universal Composable Security of Quantum Key Distribution
TL;DR: A universal composability theorem for the quantum setting is derived that shows that keys generated by repeated runs of QKD degrade slowly and can indeed be safely used, a property ofQKD that is hitherto unproven.

Deterministic secure direct communication using GHZ states and swapping quantum entanglement
TL;DR: A deterministic secure direct communication scheme via entanglement swapping, where a set of ordered maximally entangled three-particle states (GHZ states), initially shared by three spatially separated parties, Alice, Bob and Charlie, functions as a quantum information channel.
