Heralded generation of multiphoton entanglement
Philip Walther, Markus Aspelmeyer, Anton Zeilinger
We present a scheme, based only on linear optics and standard photon detection, that allows to generate heralded multiphoton entangled states of arbitrary photon number from sponta…
Radiation-pressure self-cooling of a micromirror in a cryogenic environment
Simon Groeblacher, Sylvain Gigan, Hannes R. Boehm +2
We demonstrate radiation-pressure cavity-cooling of a mechanical mode of a micromirror starting from cryogenic temperatures. To achieve that, a high-finesse Fabry-Perot cavity (F\a…
An experimental test of non-local realism
Simon Groeblacher, Tomasz Paterek, Rainer Kaltenbaek +4
Most working scientists hold fast to the concept of 'realism' - a viewpoint according to which an external reality exists independent of observation. But quantum physics has shatte…
Experimental teleportation of quantum entanglement with an optimal linear optics Bell-state analyzer
Thomas Jennewein, Rupert Ursin, Markus Aspelmeyer +1
We demonstrate an experiment on entanglement swapping using an optimal Bell-state measurement capable of identifying two of the four Bell-states for polarization entangled photons,…
