Recent advances in teleportation of entanglement and in fullerene interference

Abstract

Extending earlier results on photon teleportation and entanglement swapping it was recently possible to teleport one photon of an entangled pair such that a statistically significant violation of Bell inequality between the other member of the original pair and the teleported one was obtained. This constitutes a definite confirmation of the quantum nature of our photon entanglement procedure. It also implied that the teleported state not only was unknown, it was even undefined at the moment of teleportation. In a parallel development in fullerence interference a precision measurement of the Heisenberg uncertainty relation for these large molecules was achieved. Furthermore, more recently, we were able to realise experimentally diffraction of fullerene molecules at standing light waves.
