论文摘要
我们考虑通过可分离的目标系统A-B-C与标量场的单个局部瞬时相互作用来提取三方纠缠的问题。我们发现，在这种情况下，在这种情况下很容易提取三方纠缠，这与两部分提取的形成鲜明对比，这是由于无定理而不可能的。三方纠缠是GHz型的，并且存在最大的耦合值的最佳值。
We consider the problem of extracting tripartite entanglement through single local instantaneous interactions of a separable target system A-B-C with a scalar field. We find, non-perturbatively, that tripartite entanglement is easily extracted in this scenario, in strong contrast to bipartite extraction, which is not possible due to a no-go theorem. The tripartite entanglement is of the GHZ-type, and an optimal value of the coupling exists that admits maximal extraction.
