Towards single site addressability of ultracold atoms in optical lattices

I will describe the progress in the setup of a new experiment utilizing an ultra-high resolution imaging system to achieve first single site detection and later single site manipulation. The resolution will be 300nm, which is smaller than the lattice spacing of the infrared lattice. The aim of our project is to prepare and to study single one- and two dimensional quantum systems. Single site addressability will allow us to modify or perturb the system on a local scale and to observe the ensuing dynamics of the many-body system in real time. Quantum gates and entanglement between neighbouring atoms can, for example, be obtained by collisions in a spin-dependent lattice. We intend to load the ultracold atoms into the lattice from an all optical Bose-Einstein condensate generated in a dynamically compressed crossed optical dipole trap formed by a 50 W YAG laser.
