Towards coherent Rydberg excitation of neutral atoms in periodical optical dipole trap arrays

Jan-Niklas Schmidt
Technische Universität Darmstadt

The work presented in this talk is part of the QUIPS experiment (Quantum
Information Processing Systems) in the research group of Prof. Dr. G. Birkl at TU
Darmstadt. In that experiment neutral 85Rb atoms are cooled in a magneto-optical
trap (MOT) and then loaded into a two-dimensional register of optical dipole traps in
order to implement a universal set of quantum gates needed for quantum
computation.
The talk gives a short summary of the current status of the experimental set-up. It
describes the difficulties of the two-photon excitation scheme and explains the
adjustments done in the last months in order to demonstrate coherent Rydberg
excitation in periodical optical dipole registers.
