Scheme for the implementation of 1 → 3 optimal phase-covariant quantum cloning in ion-trap systems

Abstract

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.

Scheme for Implementation of Ancillary-Free 1 → 3 Optimal Phase-Covariant Quantum Cloning with Trapped Ions

Rong‐Can Yang, Hongcai Li, Lin Xiu +2 more

We propose a simple scheme for the implementation of the ancillary-free 1 → 3 optimal phase-covariant quantum cloning for x-y equatorial qubits in ion-trap system. In the scheme, the vibrational mode is only virtually excited, which is very important in view of decoherence. The present proposal can be realized based on current available technologies.

Implementation of a quantum cloning machine via an ion-trap system

Tao Wu, Bao‐Long Fang, Liu Ye

We propose a scheme to realize a quantum cloning machine in an ion-trap system. In the scheme, the optimal 1→2 symmetric universal quantum cloning and the optimal 1→2 phase-covariant quantum cloning can be realized. The required experimental techniques of the scheme are in the range of what can be obtained in the ion-trap setup. Therefore, the scheme can be realized with presently available ion-trap techniques.

Implementing 1→M Phase-covariant Cloning via Preparing W State in Ion-trap System

Ai‐Dong Zhu

We present a scheme to implement 1→M phase-covariant cloning via preparing a W state in ion-trap system.In our protocol,the interactions between the N ions and the vibration mode are asymmetric.By adjusting the phases of the laser fields,a maximal fidelity can be reached.Throughout the whole procedure the vibration mode remains in the vacuum state and thus the decoherence can be suppressed effectively.

Schemes to Implement the Optimal Asymmetric Economical 1→2 and 1→3 Phase-Covariant Cloning in Ion-Trap System

Ye Liu

We propose experimentally feasible schemes to implement the optimal asymmetric economical 1→2 and 1→3 phase-covariant cloning,which work without ancilla,in the context of ion-trap system.In these schemes the collective motional mode is initially prepared in the vacuum state |0.In the first scheme,we drive the first ion with a laser beam firstly,and then we map the motional mode state to the second ion.And in the second scheme,we drive two ions with different laser beams,and then we map the motional mode state to the third one.The schemes are based on resonant sideband excitation,thus they may be realized with current ion-trap techniques.
