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

Quantum-noise randomized data encryption for wavelength-division-multiplexed fiber-optic networks
TL;DR: High-rate randomized data-encryption through optical fibers using the inherent quantum-measurement noise of coherent states of light is demonstrated using a 10 Gbit/s data-bearing, in-line amplified 200-km-long line.

Optimal phase covariant cloning for qubits and qutrits
TL;DR: In this article, the optimal cloning maps for equatorial qubits and qutrits were derived without simplifying assumptions from first principles, for any number of input and output qubits, and for a single-input qubit and a single output qubit.

Concurrent Entanglement Routing for Quantum Networks: Model and Designs
Shouqian Shi,Chen Qian +1 more
TL;DR: Evaluation results show that the proposed algorithm Q-CAST increases the number of successful long-distance entanglements by a big margin compared to other methods, and may encourage more network researchers to study the entanglement routing problem.
