标题： Engineering superpositions of N00N states using an asymmetric non-linear Mach-Zehnder interferometer

摘要： 我们重新审视一种方法，该方法使用非对称非线性迈克尔逊-泽德曼干涉仪（ANLMZI）将任意单模纯态映射到N00N态的叠加态。 这种方法将允许人们定制N00N态的叠加态，其中双模联合光子数分布的每个轴都由任意单模纯态的统计特性加权。 ANLMZI的非线性以$\chi^{\left(3\right)}$自 Kerr 相互作用的形式出现在干涉仪的一个中间模式上。 受在分束器上发生的非经典干涉效应的启发，我们引入了逆向工程技术，旨在推导出生成N00N态叠加态的最佳变换。 这些技术足够通用，可以用于探索生成具有任何期望量子特性的状态的方法。 显示英文摘要

摘要： We revisit a method for mapping arbitrary single-mode pure states into superpositions of N00N states using an asymmetric non-linear Mach-Zehnder interferometer (ANLMZI). This method would allow for one to tailor-make superpositions of N00N states where each axis of the two-mode joint-photon number distribution is weighted by the statistics of any single-mode pure state. The non-linearity of the ANLMZI comes in the form of a $\chi^{\left(3\right)}$ self-Kerr interaction occurring on one of the intermediary modes of the interferometer. Motivated by the non-classical interference effects that occur at a beam splitter, we introduce inverse-engineering techniques aimed towards extrapolating optimal transformations for generating N00N state superpositions. These techniques are general enough so as to be employed to probe the means of generating states of any desired quantum properties.
