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

Entangled photon-pair sources based on three-wave mixing in bulk crystals.
TL;DR: This manuscript provides a review of the state-of-the-art bulk-optics-based SPDC sources with continuous wave pump and discusses some of the main considerations when building for deployment.

Joint measurements of spin, operational locality, and uncertainty
TL;DR: In this paper, a spin-1/2 particle was measured along any two directions, and it was shown how to obtain a bound on how sharp the joint measurement can be.

Efficient W-state entanglement concentration using quantum-dot and optical microcavities
Yu-Bo Sheng,Lan Zhou +1 more
TL;DR: In this paper, an entanglement concentration protocol (ECP) for the less-entangled W-state with quantum-dot and microcavity coupled systems was presented, which uses quantum nondemolition measurement on the spin parity to construct the hybrid parity check gate.

Quantum from Principles
TL;DR: In this paper, the authors defined a class of theories of information, which are extensions of probability theory in which events can be connected into networks, and formulated the six principles as rules governing the control and the accessibility of information.
