Testing Bell Inequalities in Photonic Crystals
During the past twenty years, a number of interesting experiments for testing the Bell Inequalities have been proposed and carried out[l]. However in all these photon experiments low detection efficiency combined with low analyzing speed of the results prevented the complete closure of the detection and/or the communication loophole. We propose a scheme to prepare entangled atomic pairs in a photonic crystal. We anticipate that the potential of using optically separated transitions along with the stability of the entangled state to spontaneous emission could potentially close both the communication and the detection loophole appearing in experiments so far.
