Quantum Manipulations Using Rydberg Atoms

Abstract

The strong, long-range interactions between Rydberg atoms may be an excellent means of producing entanglement between atoms at distances that are resolvable by conventional. In particular, using Rydberg states o block the production of multi-atom excited states appears promising for producing robust entanglement of atomic ensembles. I will present ideas for sing Rydberg blockade to achieve single atom and single photon surces, teleportation, and fast qubit readout. I will describe an appratus we ave built at Wisconsin to try to investigate Rydberg blockade of qubit pairs and ensembles, and present results on addressble ubit manipulation. Preliminary experiments o Rydberg excitation will be described.
