Recovering part of the quantum boundary from information causality
Jonathan Allcock, Nicolas Brunner, Marcin Pawlowski +1
Recently, the principle of information causality has appeared as a good candidate for an information-theoretic principle that would single out quantum correlations among more gener…
Phase shift of a weak coherent beam induced by a single atom
Syed Abdullah Aljunid, Meng Khoon Tey, Brenda Chng +4
We report on a direct measurement of a phase shift on a weak coherent beam by a single Rb-87 atom in a Mach-Zehnder interferometer. A maximum phase shift of about 1 degree is obser…
Device-independent quantum key distribution secure against collective attacks
Stefano Pironio, Antonio Acin, Nicolas Brunner +3
Device-independent quantum key distribution (DIQKD) represents a relaxation of the security assumptions made in usual quantum key distribution (QKD). As in usual QKD, the security…
