标题： On the generation and identification of optical Schrödinger cats

摘要： 我们讨论通过Wigner函数的层析重建来生成和检测宏观叠加态的可能性，即两个相干态的宏观叠加。 该叠加态是通过在与相干态纠缠的探测光子的偏振上进行条件测量而产生的。 纠缠是通过在马赫-曾德尔干涉仪中插入克尔细胞获得的。 同时给出了一些关于生成GHZ态的提示。 显示英文摘要

摘要： We discuss the possibility of generating and detecting, by a tomographic reconstruction of the Wigner function, a macroscopic superposition of two coherent states. The superposition state is created using a conditioned measurement on the polarisation of a probe photon entangled to a coherent state. The entanglement is obtained using a Kerr cell inserted in a Mach-Zender interferometer. Some hint about generation of GHZ states is given as well.
