Description
Summary:We demonstrate the production of micron-sized high-density atom clouds of interest for mesoscopic quantum information processing. We evaporate atoms from 60 {mu}K, 3x10{sup 14} atoms/cm{sup 3} samples contained in a highly anisotropic optical lattice formed by interfering diffracted beams from a holographic phase plate. After evaporating to 1 {mu}K by lowering the confining potential, in less than a second the atom density reduces to 8x10{sup 13} cm{sup -3} at a phase space density approaching unity. Adiabatic recompression of the atoms then increases the density to levels in excess of 1x10{sup 15} cm{sup -3}. The resulting clouds are typically 8 {mu}m in the longest dimension. Such samples are small enough to enable mesoscopic quantum manipulation using the Rydberg blockade and have the high densities required to investigate collision phenomena.
