Experimental Schmidt Decomposition and Entanglement Detection
Wieslaw Laskowski, Daniel Richart, Christian Schwemmer +2
We introduce an experimental procedure for the detection of quantum entanglement of an unknown quantum state with as few measurements as possible. The method requires neither a pri…

Useful Multiparticle Entanglement and Sub-Shot-Noise Sensitivity in Experimental Phase Estimation
Roland Krischek, Christian Schwemmer, Witlef Wieczorek +4
We experimentally demonstrate a general criterion to identify entangled states useful for the estimation of an unknown phase shift with a sensitivity higher than the shot-noise lim…
