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

Repeat-Until-Success quantum computing using stationary and flying qubits
TL;DR: In this article, an architecture for robust and scalable quantum computation using both stationary qubits (e.g., single photon sources made out of trapped atoms, molecules, ions, quantum dots, or defect centers in solids) and flying qubits was introduced.
Journal ArticleDOI
Quantum Cryptography
TL;DR: The theory of quantum cryptography, its potential relevance and the development of a prototype system at Los Alamos, which utilises the phenomenon of single-photon interference to perform quantum cryptography over an optical fiber communications link are described.

Entanglement as measure of electron–electron correlation in quantum chemistry calculations
Zhen Huang,Sabre Kais +1 more
TL;DR: In this paper, the entanglement can be used as an alternative measure of the electron correlation in quantum chemistry calculations, and it is one of the most striking properties of quantum mechanics.

A classical leash for a quantum system: command of quantum systems via rigidity of CHSH games
TL;DR: A rigidity theorem is proved for the famous Clauser-Horne-Shimony-Holt (CHSH) game and allows us to establish that a quantum interactive proof system with a classical verifier is as powerful as one with a quantum verifier, or QMIP = MIP*.
