摘要：
We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1 -> 2 phase- covariant telecloning, which works without ancilla, based on Cavity- QED. Our scheme is insensitive to the cavity field states and cavity decay. During the telecloning process, the cavity is only virtually excited, thus it greatly prolongs the efficient decoherent time. Therefore, the scheme can be experimentally realized in the range of current cavity QED techniques.
