SUMMARY:Quantum gates and simulations  with Rydberg atoms in a lattice
 \, R. G. Herb Condensed Matter Seminar\, David Petrosyan\, Institute o
 f Electronic Structure and Laser\, FORTH\, Heraklion\, Crete\, Greece
DESCRIPTION:Atoms in highly excited Rydberg states posses unique prope
 rties\, including long lifetimes and large dipole moments. Laser excit
 ation of atoms to the Rydberg states then provides a well controlled m
 echanism for switchable interatomic interactions\, which has been wide
 ly used to realize quantum gates and quantum simulations with cold ato
 ms in arrays of microtraps. I will discuss some of our recent research
  on these topics. In particular\, I will describe the energy spectrum 
 and microscopic dynamics of transitions to spatially-ordered states in
  finite-size chains of atoms realizing the quantum Ising model. I will
  then show how these results can be used to implement quantum gates be
 tween distant atoms in a lattice mediated by a Rydberg excitation anti
 ferromagnet.
