    "abstract": "Two trapped ions that are kilometers apart can be entangled by the joint\ndetection of two photons, each coming from one of the ions, in a basis of\nentangled states. Such a detection is possible with linear optical elements.\nThe use of two-photon interference allows entanglement distribution without\ninterferometric sensitivity to the path length of the photons. The present\nmethod of creating entangled ions also opens up the possibility of a\nloophole-free test of Bell\u0027s inequalities.",
