Title: 最优压缩以最小化对损耗的敏感性

Abstract: Non-Gaussian states, described by Wigner quasi-probability distribution taking negative values, are of great interest for various applications of quantum physics. It is known however that they are highly vulnerable to dissipation. In this paper, we show that the robustness of the non-Gaussian states to losses can be significantly improved by pre-squeezing of the quantum state, and find the optimal parameters of the squeezing. As specific examples, we consider such well-known quantum states as Schrodinger cat, Fock , and ``banana'' ones. Show Chinese abstract

Abstract: 非高斯态由取负值的威格纳准概率分布描述，在量子物理的各种应用中具有重要意义。 然而众所周知，它们极易受到耗散的影响。 在本文中，我们表明通过预压缩量子态可以显著提高非高斯态对损耗的鲁棒性，并找到压缩的最佳参数。 作为具体例子，我们考虑如薛定谔猫态、福克态和“香蕉”态这样的著名量子态。
