    "abstract": "We propose a scheme to implement the $1\\to2$ universal quantum cloning\nmachine of Buzek et.al [Phys. Rev.A 54, 1844(1996)] in the context of cavity\nQED. The scheme requires cavity-assisted collision processes between atoms,\nwhich cross through nonresonant cavity fields in the vacuum states. The cavity\nfields are only virtually excited to face the decoherence problem. That\u0027s why\nthe requirements on the cavity quality factor can be loosened.",
