Scheme for the generation of three-atom Greenberger–Horne–Zeilinger states and teleportation of entangled atomic states

Abstract

A scheme is proposed for the preparation of Greenberger–Horne–Zeilinger states for three atoms and for teleportation of an entangled atom pair by use of the triplet in cavity QED. The cavity is only virtually excited, and thus the scheme is insensitive to the cavity field states and the cavity decay. The preparation and teleportation can be achieved in a simple way.

A simplified scheme for realizing Greenberger-Horne-Zeilinger states

Shi-Biao Zheng

In the context of cavity QED a scheme is proposed for the generation of Greenberger-Horne-Zeilinger (GHZ) states. In the scheme three appropriately prepared atoms are sent through an initially empty cavity. Choosing the interaction time of each atom with the field appropriately, the three atoms are finally in a state having the GHZ form. The scheme is easily generalized for preparing n -atom entangled states.

Schemes for Greenberger–Horne–Zeilinger and cluster state preparation

Jie Song, Yan Xia, He‐Shan Song

Schemes to generate Greenberger–Horne–Zeilinger (GHZ) and cluster states of three atoms are proposed in a two-mode cavity. The advantages of the schemes are their robustness against decoherence due to spontaneous emission of the excited states and decay of the cavity modes. Moreover, the schemes can be generalized to generate N -atom entangled states.

Teleportation of unknown atomic entangled states via Greenberger–Horne–Zeilinger class states

K -W Xiong

A physical scheme for teleporting unknown atomic entangled states via three-atom non-maximally entangled states is proposed in cavity quantum electrodynamics. In this scheme, the Greenberger–Horne–Zeilinger class states are used as quantum channels. The most distinct feature of our scheme is that, not only the effects of the cavity decay and thermal field are eliminated, but also the teleportation and distillation procedure can be realized simultaneously.PACS Nos.: 03.67.Hk, 03.67.Pp

Scheme for Teleportation of four-qubit cluster-class State in Cavity QED

Xuewen Wang, Biao He, Zao Yi +2 more

We present a feasible scheme for teleportation of four-qubit cluster-class state in cavity QED. Two Greenherg-Horne-Zeilinger (GHZ) pairs are chosen as the quantum channel. By using the atom-cavity field interaction in the dispersive regime and with the assistance of a strong classical field, we can prepare the entangled quantum channel, accomplish the joint three-qubit measurement and then teleport the cluster-class state from the sender (Alice) to the Receiver (Bob) successfully. It is noted that this scheme is insensitive to both the cavity decay and the thermal field.

One-step preparation of three-particle Greenberger–Horne–Zeilinger states in cavity quantum electrodynamics

Zi-hong Chen, Pei Pei, Feng‐Yang Zhang +1 more

We propose two schemes to one-step generate the three-particle Greenberger–Horne–Zeilinger state based on the resonant atom–cavity fields interaction. The whole process may be realized experimentally providing that simple apparatus, initial conditions, and some manipulation in principle are achieved. Finally, in the current or the near future experiment parameter, we show that the proposed schemes can maintain the state with high fidelity under the condition of atomic spontaneous emission and decay of cavity fields.

Scalable cavity-QED-based scheme of generating entanglement of atoms and of cavity fields

Jaehak Lee, Jiyong Park, Sang Min Lee +2 more

We propose a cavity-QED-based scheme of generating entanglement between atoms. The scheme is scalable to an arbitrary number of atoms, and can be used to generate a variety of multipartite entangled states such as the Greenberger-Horne-Zeilinger, $W$, and cluster states. Furthermore, with a role switching of atoms with photons, the scheme can be used to generate entanglement between cavity fields. We also introduce a scheme that can generate an arbitrary multipartite field graph state.
