QES Seminar, 4/26/10: Integrated photon-atom interface for quantum information(More about event)
Institute for Quantum Information Science, and Department of Physics & Astronomy
University of Calgary, Canada
Quantum memory, or the interface between traveling and stationary carriers of quantum information, light and atoms, constitutes a key element for quantum repeaters . 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.
I will briefly introduce the importance of quantum memory for the future of long-distance quantum communication, outline a specific approach to quantum memory based on photon-echoes , and present the first demonstration of a quantum memory protocol in a waveguiding media, namely a Ti:Tm:LiNbO3 waveguide cooled to 3K. This integrated approach allows high-speed, electro-optic control of quantum state evolution during storage and is promising for integration with fibre technology and into future fibre optic quantum networks.
