Quantum teleportation between light and matter — •Hanna Krauter1, Jacob Sherson1, Rasmus Olsson1, Brian Julsgaard1, Klemens Hammerer2, Ignacio Cirac2, and Eugene Polzik1 — 1Niels Bohr Institute, Blegdamsvej 17, Copenhagen, Denmark — 2Max Planck Institut für Quantenoptik, Hans-Kopfermann-Str. 1, Garching, Germany
In this talk the first experimental demonstration of interspecies teleportation between an atomic and a photonic object will be discussed.
The state of a mesoscopic light pulse containing up to a few hundred photons is transferred onto the collective state of an atomic ensemble of 10^12 Cesium atoms over a distance of 0.5m. This is an important step towards e.g. distributed quantum networks.
The general principles of disembodied transfer via teleportation will be introduced and our physical implementation presented in greater detail. Furthermore the possibility to improve the protocol by including higher order temporal modes and the use of a squeezed light beam will be discussed.
