Physics Colloquium Series
Reid Hall, Room 101
Dr. Wolfgang Tittel will present "How to catch a photon"
The use of light to carry information, and the reversible transfer of information between light and a stationary carrier, e.g. a computer hard disk, are necessary ingredients for modern Information and Communications Technology (ICT). Quantum communications rely on similar primitives, however, with significantly more severe constraints stemming from the impossibility to amplify encoded quantum information. The possibility "to catch a photon" is interesting from a fundamental point of view and paves the path towards the quantum repeater, which will ultimately allow quantum communications over arbitrary distances.
