| Abstract: | A new conditional scheme for generating Bell states of two spatially separated high-Q cavities is reported. Our method is based on the passage of one atom only through the two cavities. A distinctive feature
of our treatment is that it incorporates from the very beginning the unavoidable presence of fluctuations in the atom-cavity
interaction times. The possibility of successfully implementing our proposal against cavity losses and atomic spontaneous
decay is carefully discussed.
