Talk by Wolfgang Tittel, University of Calgary

Quantum memory constitutes a key element for quantum repeaters, which promise overcoming the distance barrier of quantum communication. Impressive experimental and theoretical progress has been reported over the past few years and gives hope that a workable quantum memory can eventually be built.

We will present our latest results of storage of light in a

Ti:Tm:LiNbO_3 waveguide cooled to 3 Kelvin using a photon echo quantum memory protocol. In particular, we will preset storage of sub ns pulses, simultaneous storage of more than hundred modes, and discuss progress towards storage of entangled photons.
