摘要

论文研究了通过测量双模式纠缠高斯态的一个模式中的粒子数量而生成的一组非高斯态。研究表明，所有生成的状态都取决于两类参数：一些参数负责高斯特性，而另一些参数负责非高斯特性。在所有生成的状态中，我们确定了那些在生成概率和非高斯性大小方面最优的状态。

Estimation of the set of states obtained in particle number measurement schemes

The paper investigated a set of non-Gaussian states generated by measuring the number of particles in one of the modes of a two-mode entangled Gaussian state. It was demonstrated that all generated states depend on two types of parameters: some parameters are responsible for Gaussian characteristics, while other parameters are responsible for non-Gaussian characteristics. Among all generated states, we identified those optimally generated in terms of the generation probability and the magnitude of non-Gaussianity.
