SCHEME TO IMPLEMENT THE OPTIMAL ASYMMETRIC ECONOMICAL 1 → 2 PHASE-COVARIANT TELECLONING VIA CAVITY-QED

Abstract

We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1 → 2 phase-covariant telecloning, which works without ancilla, based on Cavity-QED. Our scheme is insensitive to the cavity field states and cavity decay. During the telecloning process, the cavity is only virtually excited, thus it greatly prolongs the efficient decoherent time. Therefore, the scheme can be experimentally realized in the range of current cavity QED techniques.

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.

Scheme to Implement Optimal Asymmetric Economical Phase-Covariant Quantum Cloning in Cavity QED

Wen‐Hai Zhang, Dai Jie-lin, Ye Liu

We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1 → 2 phase-covariant quantum cloning in two dimensions based on the cavity QED technique. The protocol is very simple and only two atoms are required. Our scheme is insensitive to the cavity field states and cavity decay. During the processes, the cavity is only virtually excited and it thus greatly prolongs the efficient decoherent time. Therefore, it may be realized in experiment.

We propose an experimentally feasible scheme to implement the optimal asymmetric economical 1→3 phase-covariant cloning, which works without ancilla, based on cavity QED. In our scheme, two of the three atoms simultaneously interact with a cavity field and they are driven by classical fields. The scheme is insensitive to the cavity field states and the cavity decay.

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.
