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 And Relativistic Protocols For Secure Multi-Party Computation
TL;DR: A new protocol for non-relativistic strong coin tossing is introduced, which matches the security of the best protocol known to date while using a conceptually different approach to achieve the task.

Strongly correlated two-photon transport in a one-dimensional waveguide coupled to a two-level system.
Jung-Tsung Shen,Shanhui Fan +1 more
TL;DR: It is shown that two-photon transport is strongly correlated in one-dimensional waveguide coupled to a two-level system and the scattering eigenstates of this system include a two -photon bound state that passes through the two- level system as a composite single particle.

Secure device-independent quantum key distribution with causally independent measurement devices
TL;DR: This work shows that device-independent QKD is possible with key rates comparable to those of standard schemes, and provides a general security proof for a large class of protocols in a model in which the raw key is generated by independent measurements.

Differential phase shift quantum key distribution.
TL;DR: In this paper, a linear superposition state of three basis kets was proposed, where a photon split to three pulses is sent from Alice to Bob, where the phase difference between sequential two pulses carries bit information.

Quantum information with Gaussian states
TL;DR: This work reviews the properties and applications of Gaussian states in quantum information with emphasis on the fundamental concepts, the calculation techniques and the effects of imperfections of the real-life experimental setups.
