My First Paper on quant-ph


在导师的首肯下,我折腾了一下午,终于成功往quant-ph上投了一篇论文。

A multi-atom and resonant interaction scheme for quantum state transfer and logical gates between two remote cavities via an optical fibre

Authors: Zhang-qi Yin and Fu-li Li

A system consisting of two single-mode cavities spatially separated and connected by an optical fibre and multi two-level atoms trapped in the cavities is considered. If the atoms resonantly and collectively interact with the local cavity fields but there is no direct interaction between the atoms, we show that an ideal quantum state transfer, and highly reliable quantum swap, entangling and controlled-Z gates can be deterministically realized between the distant cavities. We find that the operation of the state-transfer, and swap, entangling and controlled-Z gates can be greatly speeded up as number of the atoms in the cavities increases. We also notice that the effects of spontaneous emission of atoms and photon leakage out of cavity on the quantum processes can also be greatly diminished in the multi-atom case.

论文的地址是:quant-ph/0606152,现在还没有公布,明天(20号)才能够从网上看到。这篇论文也就是我前些天提过的那篇投稿的论文。我新建了一个论文列表页面,列出了我所有完成的论文,到目前为止只有两篇。我会及时的更新这个页面的。

更新:现在已经可以从arxiv上看到这篇论文了。
