本工作提出一种产生粒子数相差4或8的福克态叠加态的方案，该协议基于对多模高斯态的光子数分辨测量。我们将产生的态与多组分薛定谔猫态进行比较，评估保真度并确定其随探测粒子数的缩放规律，还推导了产生此类态的最优配置。
英文摘要
In this work, we propose a scheme for generating superpositions of Fock states whose numbers differ by four or eight. The proposed protocol is based on photon-number-resolving measurements on multimode Gaussian states. We compare of the generated states with multicomponent Schrödinger cat states. We evaluate the fidelity and determine how it scales with the number of detected particles. Furthermore, we derive the optimal configuration for the generation such states.
