Abstract

We propose a scheme to implement 1 → M economical phase-covariant quantum cloning by using N three-level atoms nonresonantly interacting with a cavity assisted by a classical laser field. Using this interaction 1 → M telecloning is also implemented by applying the maximal entangled W state and partial entangled W state as the quantum channel, respectively. It is pointed out by analysing the fidelities and success probabilities that a relatively high fidelity and success probability can be obtained by choosing an appropriate channel in terms of the pre-known information of the input state.

Implementing 1 → M Economical Phase-Covariant Telecloning in Cavity QED

Xue Li, Nian-Quan Jiang

We propose an experimentally feasible scheme to implement the economical 1 → M phase-covariant telecloning based on cavity QED. By the resonant interaction of the atoms with cavity field of a high-Q cavity and the different coupling strength between atoms and cavity field, the scheme can generate quantum entanglement channel in one step. What is more, the operation time and steps do not increase with the increase of atoms.

Scheme to Implement Scheme 1 → M Economical Phase-Covariant Telecloning via Cavity QED

Qi Liu, Wen‐Hai Zhang, Ye Liu

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.

Qi Liu, Wen‐Hai Zhang, Liu Ye

A scheme to implement of 1 → 3 economic phase-covariant cloning machine for unknown equator state in cavity-QED is proposed. The scheme requires cavity-assisted collision processes between atoms, which cross through nonresonant cavity fields in the vacuum states. The cavity fields are only virtually excited so that the cavity quality factor can be loosened.

Realization of a general quantum cloning machine via cavity-assisted interaction

Bao‐Long Fang, Tao Wu, Liu Ye

We present a scheme to realize a general quantum cloning machine via cavity-assisted interaction. First, this scheme can prepare entangled states of three remote trapped atoms including the W state and the GHZ state. Based on this approach, the quantum information carried by a photon pulse or a trapped atom can be copied to other two trapped atoms. According to the known information of the initial state, the equipment can provide the optimal symmetric (asymmetric) universal and phase-covariant quantum cloning. Further, via the cavity input-output process, the quantum cloning can be realized with high fidelity, even if the atom is not localized in the Lamb-Dicke regime.
