Abstract

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.

Scheme for quantum state manipulation in coupled cavities

Jin‐Zhong Lin

By controlling the parameters of the system, the effective interaction between different atoms is achieved in different cavities. Based on the interaction, scheme to generate three-atom Greenberger–Horne–Zeilinger (GHZ) is proposed in coupled cavities. Spontaneous emission of excited states and decay of cavity modes can be suppressed efficiently. In addition, the scheme is robust against the variation of hopping rate between cavities.

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

Ye Liu, Guang‐Can Guo

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.

Robust preparation of Greenberger-Horne-Zeilinger and W states of three distant atoms

Chang‐shui Yu, X. X. Yi, He‐Shan Song +1 more

Schemes to generate Greenberger-Horne-Zeilinger (GHZ) and $W$ states of three distant atoms are proposed in this paper. The schemes use the effects of quantum statistics of indistinguishable photons emitted by the atoms inside optical cavities. The advantages of the schemes are their robustness against detection inefficiency and asynchronous emission of the photons. Moreover, in Lamb-Dicke limit, the schemes do not require the simultaneous click of the detectors. This makes the schemes more realizable in experiments.

Effective scheme for preparation of multi-atom Greenberger–Horne–Zeilinger states in coupled cavities via adiabatic passage

Si-Yang Hao, Yan Xia, Jie Song

A scheme is proposed to deterministically generate multi-atom Greenberger–Horne–Zeilinger (GHZ) states trapped in coupled cavities, which is based on the adiabatic passage of the dark state. The scheme does not need to adjust the interaction time accurately and is insensitive to the fluctuations of some experimental parameters. However, we should choose the appropriate Rabi frequencies of the classical fields to achieve the optimal characteristic of the system. In addition, we also demonstrate numerically that it is robust against decoherence caused by the cavity decay and atomic spontaneous emission.

Generation of four-atom Greenberger—Horn—Zeilinger state via adiabatic passage

Chun‐Ling Zhang, Mei-Feng Chen

We propose a scheme to generate a Greenberger—Horn—Zeilinger (GHZ) state of four atoms trapped in a two-mode optical cavity via an adiabatic passage. The scheme is robust against moderate fluctuations of the experimental parameters. Numerical calculations show that the excited probabilities of both the cavity modes and the atoms are tiny and depend on the pulse peaks of the classical laser fields. For certain decoherence due to the atomic spontaneous emission and the cavity decay, there exits a range of pulse peaks to get a high fidelity.
