DESCRIPTION:Trapped atomic ions are among the most attractive \nimplementa
 tions of quantum bits for applications in quantum information processing\,
  owing to their long trapping lifetimes and long coherence times. While ne
 arby trapped ions can be entangled through their \nCoulomb-coupled motion\
 , networking remotely-located ions requires a photonic coupling.  When two
  atomic ions each become entangled with an emitted single photon\, subsequ
 ent interference and detection of these \nphotons can leave the trapped io
 n qubits in an entangled state. Although this entanglement is probabilisti
 c\, it is not post-selective and \ntherefore can be utilized for long-dist
 ance quantum communication and large-scale quantum computation.\n
