Query: Coupled Three-Mode Squeezed Vacuum   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.
