Journal ArticleDOI
Fisher information and multiparticle entanglement
Philipp Hyllus,Philipp Hyllus,Wiesław Laskowski,Roland Krischek,Christian Schwemmer,Witlef Wieczorek,Harald Weinfurter,Luca Pezzè,Augusto Smerzi +8 more
TL;DR: Bounds on F imply that genuine multiparticle entanglement is needed for reaching the highest sensitivities in quantum interferometry, and these criteria detect different sets of states and illustrate their strengths by considering several examples.
Journal ArticleDOI
Twin Matter Waves for Interferometry Beyond the Classical Limit
Bernd Lücke,M. Scherer,J. Kruse,Luca Pezzè,Frank Deuretzbacher,Philipp Hyllus,O. Topic,Jan Peise,Wolfgang Ertmer,Jan J. Arlt,Luis Santos,Augusto Smerzi,Carsten Klempt +12 more
TL;DR: This work used spin dynamics in Bose-Einstein condensates to create large ensembles of up to 104 pair-correlated atoms with an interferometric sensitivity beyond the shot noise limit, and points the way toward a new generation of atom interferometers.
Journal ArticleDOI
Detection of entanglement with few local measurements
Otfried Gühne,Philipp Hyllus,Dagmar Bruß,Artur Ekert,Maciej Lewenstein,Chiara Macchiavello,Anna Sanpera +6 more
TL;DR: In this paper, the authors introduce a general method for the experimental detection of entanglement by performing only few local measurements, assuming some prior knowledge of the density matrix, based on the minimal decomposition of witness operators into a pseudomixture of local operators.
Journal ArticleDOI
Not all pure entangled states are useful for sub-shot-noise interferometry
TL;DR: In this article, the authors investigated the connection between the shot-noise limit in linear interferometers and particle entanglement and showed that all pure entangled states can be made useful for sub-shotnoise interferometry while for ng2$ this is not the case.
Journal ArticleDOI
Useful Multiparticle Entanglement and Sub-Shot-Noise Sensitivity in Experimental Phase Estimation
Roland Krischek,Christian Schwemmer,Witlef Wieczorek,Harald Weinfurter,Philipp Hyllus,Luca Pezzè,Augusto Smerzi +6 more
TL;DR: A general criterion to identify entangled states useful for the estimation of an unknown phase shift with a sensitivity higher than the shot-noise limit is experimentally demonstrated.
