Towards High-Speed Optical Quantum Memories.
Dr. Virginia Lorenz
University of Delaware

Quantum memories, capable of controllably storing and releasing a photon, are a crucial component for quantum computing and quantum communication. The majority of quantum memories to date have operated with bandwidths that limit data rates to megahertz. I will present results demonstrating the coherent storage and retrieval of sub-nanosecond low-intensity light pulses with spectral bandwidths exceeding 1 GHz in cesium vapor. The novel memory interaction takes place through a far off-resonant two-photon transition in which the memory bandwidth is dynamically generated by a strong control field.
