摘　　要：This paper proposes a scheme for the implementation of 1→ 3 optimal phase-covariant quantum cloning with trapped ions. In the present protocol, the required time for the whole procedure is short due to the resonant interaction, which is important in view of decoherence. Furthermore, the scheme is feasible based on current technologies.This paper proposes a scheme for the implementation of 1→ 3 optimal phase-covariant quantum cloning with trapped ions.
