摘　　要：We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1→3 phasecovariant telecloning protocol, which works without ancilla, based on cavity quantum electrodynamics （QED）. The scheme is insensitive to the cavity field states and the cavity decay. In the telecloning process, the cavity is only virtually excited, it greatly prolongs the efficient decoherent time. Therefore, the scheme may be experimentally realized in the field of current cavity QED techniques.We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1→3 phasecovariant telecloning protocol, which works without ancilla, based on cavity quantum electrodynamics （QED）.
