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.

Direct Measurement of Decoherence for Entanglement between a Photon and Stored Atomic Excitation

TL;DR: An investigation of the Bell violation as a function of the cross correlation between the generated nonclassical fields is reported, with saturation of the violation close to the maximum value allowed by quantum mechanics.

Nonlinear model dynamics for closed-system, constrained, maximal-entropy-generation relaxation by energy redistribution.

TL;DR: A nonlinear model for relaxation by energy redistribution within an isolated, closed system composed of noninteracting identical particles with energy levels with time-dependent occupation probabilities assumed to obey the nonlinear rate equations.

Quantum entanglement as a quantifiable resource

TL;DR: This paper reviews two such uses of entanglement, called ‘teleportation’ and ‘dense coding’, and considers novel features that arise when entangled objects are shared among three objects.
