Abstract
A linear optical scheme is proposed for implementing a nonlocal cloning machine which copies a state near a given one with single-photon interference. We combine the advantages of photons and atoms by adopting two three level atoms as the storing qubits and a polarized photon as the flying qubit, and the photon loss events are also considered. With our present scheme, a high-fidelity cloning machine is realized at the expense of the success probability.
