    "abstract": "We consider a system consisting of a $\\Lambda$-type atom and a V-type atom,\nwhich are individually trapped in two spatially separated cavities that are\nconnected by an optical fibre. We show that an extremely entangled state of the\ntwo atoms can be deterministically generated through both photon emission of\nthe $\\Lambda$-type atom and photon absorption of the V-type atom in an ideal\nsituation. The influence of various decoherence processes such as spontaneous\nemission and photon loss on the fidelity of the entangled state is also\ninvestigated. We find that the effect of photon leakage out of the fibre on the\nfidelity can be greatly diminished in some special cases. As regards the effect\nof spontaneous emission and photon loss from the cavities, we find that the\npresent scheme with a fidelity higher than 0.98 may be realized under current\nexperiment conditions.",
