SUMMARY:Long range interactions between Rydberg atoms\, Physics Depart
 ment Colloquium\, Saffman\, University of Wisconsin-Madison
DESCRIPTION:Interactions between Rydberg states of neutral atoms are a
  promising approach for  fast and long range quantum gates. We have de
 monstrated that a single Rydberg excited Rb atom  blocks  excitation o
 f a second atom located more than 10 microns away.  The observed proba
 bility of double excitation of < 20% is consistent  with a theoretical
   model of the Rydberg  interaction. Progress towards using blockade t
 o demonstrate a quantum CNOT gate with neutral atoms as well as ideas 
 for creating multiqubit entanglement will be presented.
