Long-distance single photon transmission from a trapped ion via quantum frequency conversion

Thomas Walker

University of Sussex

Thomas Walker is a research student doing his PhD with the ITCM group at the university of Sussex. He is working with trapped ions coupled to optical cavities to develop techniques for networked quantum computing and quantum communications.


Trapped atomic ions are ideal single photon emitters with long lived internal states which can be entangled with emitted photons. Coupling the ion to an optical cavity enables efficient emission of single photons into a single... [ view full abstract ]
