摘　　要：We propose an experimentally feasible scheme to implement the economical 1 → M （ M = 2k ＋ 1） phase-covariant telecloning without ancilla based on cavity QED. The scheme requires cavity-assisted collision processes between atoms, which cross through the off-resonant cavity field in the vacuum states. During the telecloning process, the cavity is only virtually excited and it thus greatly prolongs the efficient decoherent time. Therefore, our scheme may be realized in experiment in future.We propose an experimentally feasible scheme to implement the economical 1 → M （ M = 2k ＋ 1） phase-covariant telecloning without ancilla based on cavity QED.
