DESCRIPTION:Atoms in highly excited Rydberg states exhibit strong  \ninter
 actions over distance scales of a few microns. In our work we  \nexploit t
 he enhanced sensitivity of Rydberg states to control the  \npropagation of
  light through an atomic ensemble. For example\, if the  \natoms are prepa
 red in a superposition of ground and Rydberg states  \n[1] the medium acqu
 ires a giant electro-optic effect many orders of  \nmagnitude larger than 
 other systems [2]. Our eventual goal is to  \nexploit this giant non-linea
 rity to control pulse propagation at the  \nsingle photon level.\n\n[1] AK
