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…

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…
