Quantum Manipulations Using Rydberg Atoms
Thad Walker Department of Physics University of
Wisconsin, Madison
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 optics. In particular, using
Rydberg states to block the production of
multi-atom excited states appears promising for
producing robust entanglement of atomic
ensembles. I will present ideas for using
Rydberg blockade to achieve single atom and
single photon sources, teleportation, and fast
qubit readout. I will describe an apparatus we
have built at Wisconsin to try to investigate
Rydberg blockade of qubit pairs and ensembles,
and present results on addressable qubit
manipulation. Preliminary experiments on Rydberg
excitation will be described.
