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

Bidirectional quantum key distribution protocol with practical faint laser pulses
Fu-Guo Deng,Gui-Lu Long +1 more
TL;DR: A two-way protocol for the quantum key distribution with practical faint laser pulses that is secure and close to practical conditions, and does not require the exchange of measuring basis information between Alice and Bob, hence saving a lot of storage space.

A scheme for secure direct communication using EPR pairs and teleportation
F. L. Yan,X. Q. Zhang +1 more
TL;DR: A novel scheme for secure direct communication between Alice and Bob is proposed, where there is no need for establishing a shared secret key and teleportation transmits Bob’s message without revealing any information to a potential eavesdropper.
