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

Fault tolerant three-party quantum secret sharing against collective noise
TL;DR: In this paper, the authors present two robust three-party quantum secret sharing protocols against two kinds of collective noise, where each logical qubit is made up of two physical qubits and is invariant under a collective noise.

TL;DR: The proposed matrix algorithm for quantum cryptography can be simplified to matrix multiplication, which is implemented and optimized in modern computers, and considerably information capacity can be improved effectively and efficiently by the recursive property of Fibonacci and Lucas matrices, thereby avoiding the restriction of physical conditions, such as the communication bandwidth.

A Diagrammatic Axiomatisation for Qubit Entanglement
TL;DR: This paper presents a full graphical axiomatisation of the relations between GHZ and W: the ZW calculus, which refines a version of the preexisting ZX calculus, while keeping its most desirable characteristics: undirected ness, a large degree of symmetry, and an algebraic underpinning.

Quantum cryptography: uncertainty in the service of privacy.
TL;DR: In this article, a quantum optical communications system can achieve a goal unattainable by classical mathematical means alone: to enable two parties, who share no secret Information initially, to exchange secret information even though all their transmissions are subject to monitoring by an eavesdropper.

TL;DR: This work experimentally established hyper- and hybrid entanglement in multiple degrees of freedom, including path (K-vector) and orbital angular momentum, between two separated atomic ensembles by using quantum storage, and the results are promising for achieving quantum communication and computing with many degrees offreedom.
