我们证明了利用原子-腔库来制备原子系综和光场混合系统的双模压缩和纠缠态是可能的，它们彼此之间不直接相互作用。其基本机制是基于系统和储能器之间的双模压缩相互作用和分束器相互作用的综合作用。库机制对量子网络很重要，因为它允许局域的基于物质的存储器和量子信息的光学载体之间的接口，而不需要直接相互作用。
We show that it is possible to use an atom–cavity reservoir to prepare the two-mode squeezed and entangled states of a hybrid system of an atomic ensemble and an optical field, which do not directly interact with each other. The essential mechanism is based on the combined effect of a two-mode squeezing interaction and a beam–splitter interaction between the system and the reservoir. The reservoir mechanism is important for quantum networking in that it allows an interface between a localized matter-based memory and an optical carrier of quantum information without direct interaction.
