论文摘要
我们谈到了混合相干状态(HCS)的非古老性,即表示为相干状态和单光子添加的相干(SPAC)状态的状态。特别是,我们评估了它们的光子统计数据,挤压和负函数的负效率。我们的结果表明,与SPAC状态相比,HCS可能表现出更大的非经典性。我们还建议针对HCS的生成方案,其中涉及KERR非线性和选择后。
We address nonclassicality of hybrid coherent states (HCS), i.e. states expressed as superpositions of coherent states and single-photon-added coherent (SPAC) state. In particular, we evaluate their photon statistics, squeezing, and negativity of the Wigner function. Our results indicated that HCS may exhibit larger nonclassicalities than SPAC state. We also suggest a generation scheme for HCS which involves Kerr nonlinearity and postselection.
