Abstract

我们为零的一件二模式的纠纷转建议一个计划 -- 纠缠的 orone 光子在二之间声明经由原子洞的洞回答反响的相互作用。在我们的建议,以便转移纠缠的状态,我们仅仅为收到电视需要二个相同二水平的原子和 atwo 模式洞移植状态。这个计划不要求 Bell-statemeasurement 并且执行任何转变重建起始的状态。并且转移能以一种简单方式与 100% 成功概率发生。并且为在洞之间州的纠缠的 atwo 模式转的一个网络被建议。这个计划能也被扩大转移洞州的纠缠的 N 模式。

Transferring of a Two-Mode Entangled State Between Two Cavities via Cavity QED

Tao Wu, NI Zhi-xiang, Ye Liu

We propose a scheme for transferring of a two-mode entanglement of zero- or one-photon entangled states between two cavities via atom-cavity field resonant interaction. In our proposal, in order to transfer the entangled state, we only need two identical two-level atoms and a two-mode cavity for receiving the teleported state. This scheme does not require Bell-state measurement and performing any transformations to reconstruct the initial state. And the transfer can occur with 100% success probability in a simple manner. And a network for transferring of a two-mode entangled state between cavities is suggested. This scheme can also be extended to transfer N -mode entangled state of cavity.

Scheme to transfer an atomic entangled state in cavity QED

NI Zhi-xiang

We present a scheme for transferring an unknown atomic entangled state via atom-cavity field interaction.This proposal,which has success probability of unit,is mainly employing two atoms for receiving the teleported state,and a two-mode cavity as the quantum channel.The two modes of the cavity have different frequencies and polarizations.So the two modes are distinguished by their frequencies and their orthogonal polarizations,hence they occupy distinct regions in the cavity.The atom interacts resonantly with the mode of the cavity according to the Jaynes-Cummings Hamiltonian,and when interaction between the atom and one of the two modes takes place,the other mode remains unaffected.This scheme does not require Bell-state measurement and any operations to reconstruct the initial state.This scheme can also be extended to transfer entangled state of N-atom.

我们为通过和在大去谐的限制下面开始处于一个奇怪协调的状态准备的一块单个模式的洞地的二个二水平的原子的同时的相互作用产生一个二原子的簇状态建议一个物理计划。驱散常数,这块地的紧张和准备计划上的有瑕疵的操作的影响 reinvestigated。当洞的紧张足够大时,洞腐烂的影响高效地被压制,这被显示出。当在穿过洞轴的二个原子之间的时差是小的时,在簇状态的实现的可能的错误是可以忽略的。计划能被当前的技术认识到,这被建议。

Transferring a cavity field entangled state in cavity QED

Ye Liu, Guang‐Can Guo

We propose a scheme for transferring an entanglement of zero- and one-photon states from one cavity to another. The scheme, which has 100% success probability, is mainly based on a two-mode cavity dispersively interacting with a three-level atom in the Λ configuration and does not involve Bell-state measurement. This scheme can also be used to teleport an unknown atomic state.
