交叉Kerr诱导的数压缩:一个实例研究

Verifying cross-Kerr induced number squeezing: a case study

David Schmid, Kevin Marshall, Daniel F. V. James

摘要:

我们分析了一种通过处理两个大相干态在交叉克尔介质中相互作用时产生的纠缠来产生有趣的非经典态的实验方法。我们特别研究了损失和噪音在每种实验模式中的影响,以及选择后结果的“分箱”影响。即使有这些缺陷,我们找到了一个最佳的一组目前可实现的参数,这将允许一个证明的原则演示的数量压缩状态与大的平均光子数。我们讨论了其他有用的状态,可以产生相同的实验工具,包括一类状态,其中包含不同的光子数的相干叠加,例如良好的近似状态$\frac{1}{\sqrt{2}} (|0\rangle+|20\rangle)$。最后,我们提出了一个可能的应用领域中的光学机械的这种状态。

英文摘要:

We analyze an experimental method for creating interesting nonclassical states by processing the entanglement generated when two large coherent states interact in a cross-Kerr medium. We specifically investigate the effects of loss and noise in every mode of the experiment, as well as the effect of "binning" the post-selection outcomes. Even with these imperfections, we find an optimal set of currently-achievable parameters which would allow a proof-of-principle demonstration of number squeezing in states with large mean photon number. We discuss other useful states which can be generated with the same experimental tools, including a class of states which contain coherent superpositions of differing photon numbers, e.g. good approximations to the state $\frac{1}{\sqrt{2}} (|0\rangle+|20\rangle)$. Finally, we suggest one possible application of this state in the field of optomechanics.
