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

Design and Analysis of Communication Protocols for Quantum Repeater Networks
TL;DR: In this paper, the performance of a quantum-repeater network depends on the protocol employed to distribute entanglement, and the choice of repeater-to-repeat link protocol has a profound impact on communication rate as a function of hardware parameters.

TL;DR: This paper presents a no-switching protocol and shows that switching is not required for coherent-state continuous-variable quantum key distribution, and achieves higher information rates and a simpler experimental setup compared to previous protocols that rely on switching.

Demonstration of free-space reference frame independent quantum key distribution
TL;DR: The security analysis of the RFI QKD scheme is extended to be able to deal with uncalibrated devices and a finite number of measurements, an important step towards mass production of handheld QKKD devices.
