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.

Robust general N user authentication scheme in a centralized quantum communication network via generalized GHZ states

TL;DR: A new robust General N user authentication protocol based on N-particle Greenberger–Horne–Zeilinger (GHZ) states is presented, which makes eavesdropping detection more effective and secure, as compared to some current authentication protocols.

Photon source and a method of operating a photon source

TL;DR: In this article, a photon source comprising a quantum dot comprising a confined conduction band energy level capable of being populated with at least one carrier and a confined valence band capacity to be populated by more than one carrier is provided, where the supply means are configured to regulate the supply of carriers.

Machine Learning Nonlocal Correlations.

TL;DR: Not only can the machine learn to quantify nonlocality, but discover new kinds of nonlocal correlations inaccessible with other current methods as well, and the framework is applied to distinguish between classical, quantum, and even postquantum correlations.

Quantum entanglement and classical communication through a depolarizing channel

TL;DR: In this paper, the role of entanglement for transmission of classical information through a memoryless depolarizing channel was analyzed and it was shown analytically that the mutual information cannot be increased by encoding classical bits into entangled states of two qubits.
