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

Disentanglement in a two-qubit system subjected to dissipation environments
TL;DR: In this article, the authors investigated the time evolution of entanglement of two-qubit systems exposed to either thermal or squeezed reservoirs, and they showed that the sudden death of the entangled states always exists in the thermal and squeezed reservoirs.
