Abstract

We present a scheme to prepare cluster-type entangled squeezed vacuum states (CTESVS) by considering the two-photon interaction between a two-level atom and a high-quality cavity, driven by a strong classical field. After the realization of simple atomic measurements, the generation of CTESVS in four separate cavities is accomplished within the cavity decay time. In the case of large atom–cavity detuning, the scheme is immune to the effect of atomic spontaneous emission.

Scheme for generating a cluster-type entangled squeezed vacuum state via cavity QED

文晶姬, Yeon, Kyu-Hwang +2 more

A scheme is proposed to generate an N-qubit cluster-type entangled squeezed vacuum state(CTESVS) based on the two-photon interaction between a two-level atom and the cavity fields with the cavity QED system. The CTESVS in N separate cavities can be effectively obtained after performing a simple one-qubit measurement on the atom. The influence of cavity decay on the CTESVS is also discussed.

Superposition and entanglement of mesoscopic squeezed vacuum states in cavity QED

Changyong Chen, Mang Feng, Kelin Gao

We propose a scheme to generate superposition and entanglement between the mesoscopic squeezed vacuum states by considering the two-photon interaction of $N$ two-level atoms in a cavity with high quality factor, assisted by a strong driving field. By virtue of specific choices of the cavity detuning, a number of multiparty entangled states can be prepared, including the entanglement between the atomic and the squeezed vacuum cavity states and between the squeezed vacuum states and the coherent states of the cavities. We also present how to prepare entangled states and ``Schr\"odinger cats'' states regarding the squeezed vacuum states of the cavity modes. The possible extension and application of our scheme are discussed. Our scheme is close to the reach with current cavity QED techniques.

Generation for entangled squeezed coherent states of two cavity modes A scheme is based upon three artificial three-level atoms in a doubly resonant cavity

Li-Xin Xia, Guo-Xin Xiong

we propose a scheme to produce pure and entangled squeezed coherent state. Under the strong classical driven condition, three�Σ -type artificial three-level atoms interact with a doubly resonant cavity by initially preparing the artificial atoms in certain states, successionally. It is shown that an entangled squeezed coherent state can be generated from the product state of the two cavity-mode vacuum fields.

Generation of multipartite entangled states by cavity QED

Zhang Ying-Jie, Ren Ting-Qi, Yun‐Jie Xia

We propose the methods of generating multipartite entanglement by considering the interaction of a system of N two-level atoms in M cavities of high quality factor with a strong classical driving field. It is shown that, with the cavity detuning, the applied driving field detuning and vacuum Rabi coupling, we can produce an entangled coherent state in two single-mode cavities and generate the entangled coherent cluster states in two bimodal vacuum cavities. Tuning these parameters also allows us to acquire the anti-Jaynes–Cummings (AJC) interaction, with which we can generate the maximally two-photon entangled states, and the two-atom and the two-photon entangled cluster states.
