Experimental quantum key distribution based on a Bell test
Alexander Ling, Matthew P. Peloso, Ivan Marcikic +3
We report on a complete free-space field implementation of a modified Ekert91 protocol for quantum key distribution using entangled photon pairs. For each photon pair we perform a…
Security Bounds for Quantum Cryptography with Finite Resources
Valerio Scarani, Renato Renner
A practical quantum key distribution (QKD) protocol necessarily runs in finite time and, hence, only a finite amount of communication is exchanged. This is in contrast to most of t…
Interfacing light and single atoms with a lens
Meng Khoon Tey, Gleb Maslennikov, Timothy C. H. Liew +6
We characterize the interaction between a single atom or similar microscopic system and a light field via the scattering ratio. For that, we first derive the electrical field in a…
Simulation of partial entanglement with nonsignaling resources
Nicolas Brunner, Nicolas Gisin, Sandu Popescu +1
With the goal of gaining a deeper understanding of quantum non-locality, we decompose quantum correlations into more elementary non-local correlations. We show that the correlation…
Testing the Hilbert space dimension
Nicolas Brunner, Stefano Pironio, Antonio Acin +3
Given a set of correlations originating from measurements on a quantum state of unknown Hilbert space dimension, what is the minimal dimension d necessary to describes such correla…
Testing quantum correlations versus single-particle properties within Leggett's model and beyond
Cyril Branciard, Nicolas Brunner, Nicolas Gisin +4
Quantum theory predicts and experiments confirm that nature can produce correlations between distant events that are nonlocal in the sense of violating a Bell inequality. Neverthel…
