论文摘要
多部分纠缠是各种量子信息任务的关键资源。在这里，我们提出了一种通过非线性光学过程产生真正的三方纠缠的方案。我们以fock得出的相应输出状态得出，我们称之为耦合的三模式挤压真空。我们发现由于存在耦合，在三种输出模式中的两种中，强度挤压出不直觉的行为。我们还表明，这种状态可能是真正的三方。
Multipartite entanglement is a key resource for various quantum information tasks. Here, we present a scheme for generating genuine tripartite entanglement via nonlinear optical processes. We derive, in the Fock basis, the corresponding output state which we termed the coupled three-mode squeezed vacuum. We find unintuitive behaviors arise in intensity squeezing between two of the three output modes due to the coupling present. We also show that this state can be genuinely tripartite entangled.
