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

Three-step semiquantum secure direct communication protocol
TL;DR: A method to check Eves disturbing in the doves returning phase such that Alice does not need to announce publicly any position or their coded bits value after the photons transmission is completed, and the proposed SQSDC protocol can be implemented with the existing techniques.

TL;DR: It is pointed out that in most real, practical situations, where the concept of device independence is used as a protection against unintentional flaws or failures of the quantum apparatuses, it is sufficient to show that the generated string is random with respect to an adversary that holds only classical side information; i.e., proving randomness against quantum side information is not necessary.

Quantum secure direct communication with quantum encryption based on pure entangled states
TL;DR: This paper presents a scheme for quantum secure direct communication with quantum encryption that has the advantage that the pure entangled quantum signal source is feasible at present and any eavesdropper cannot steal the message.

Separability Properties of Three-mode Gaussian States
TL;DR: In this article, a necessary and sufficient condition for the separability of tripartite three-mode Gaussian states is derived and a classification of separability properties of those systems is given.
