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.

SCHEME TO IMPLEMENT GENERAL PHASE-COVARIANT QUANTUM CLONING

Wen‐Hai Zhang, Ye Liu, Dai Jie-lin

We propose an experimentally feasible scheme to implement the optimal general 1→2 phase-covariant quantum cloning machine based on cavity QED. In the scheme, the cavity is only virtually excited and thus the scheme is insensitive to the cavity field states and cavity decay.

Phase-covariant quantum cloning in cavity QED

Ming Yang

A scheme is proposed to realize 1→2 phase-covariant quantum cloning machine in cavity electrodynamics.This clone machine acts on the electronic states of atoms that interact with electromagnetic fields of two high-Q cavities.The cavity fields are initially prepared in the vacuum states.Although CNOT operations are needed,fewer operations are required than other schemes and the basic operations(controlled quantum gates and classical field pulses)are thoughtfully tested.

Scheme to Implement the Optimal Asymmetric Economical 1→3 phase-covariant Cloning in Cavity QED

Da-Rong Qiu, Wen‐Hai Zhang, Ye Liu

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. Therefore, it may be realized in experiment.
