Title:  Progress towards fault-tolerance in atomic-ion based 
	quantum information processors

Abstract:

  In recent years, multiple groups have experimentally demonstrated
  all of the DiVincenzo criteria in ion-trap systems. Now, efforts are
  underway to build a large scale quantum information processor. For
  this goal to be realized, error rates must be suppressed to very low
  levels, and more complicated traps must be built. I will discuss our
  progress at NIST in these areas. In particular, our memory error
  during the detection interval is on the order of 10^{-5}, and
  spontaneous emission errors during a 2-qubit gate interval are in
  the neighborhood of 5 x 10^{-4}. Our experiments indicate that with
  sufficient laser power, errors due to spontaneous emission can be
  suppressed even further. I will also discuss our recent quantum
  computing experiments at NIST.
