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

Feasibility of continuous-variable quantum key distribution with noisy coherent states
Vladyslav C. Usenko,Radim Filip +1 more
TL;DR: This work considers the method of sender-side state purification to compensate the preparation noise and shows its applicability in the realistic conditions of channel loss, untrusted channel excess noise, and trusted detection noise.

Quantum cloning machines and the applications
TL;DR: A comprehensive review of quantum cloning can be found in this article, where the authors give a complete description of those important developments about quantum cloning and some related topics, and in particular, they present some detailed formulations so that further study can be taken based on those results.

Lifting Bell inequalities
TL;DR: In this article, it is shown that if the original inequality defines a facet of the polytope of local joint outcome probabilities then the lifted one also defines a more complex polytoope.

Deterministic generation of three-dimensional entanglement for two atoms separately trapped in two optical cavities
TL;DR: In this paper, a scheme for the deterministic generation of three-dimensional entanglement of two distant atoms separately trapped in two optical cavities connected by an optical fiber was proposed.
