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.

Tripartite correlation performance for use in quantum radar systems
In recent years, quantum radar has focused entirely on using bipartite squeezed states of light as a mechanism for target detection. This paper studies the performance of a quantum radar that uses a

Multi-channel entanglement distribution using spatial multiplexing from four-wave mixing in atomic vapor
Four-wave mixing in atomic vapor allows for the generation of multi-spatial-mode states of light containing many pairs of two-mode entangled vacuum beams. This in principle can be used to send

Many-particle entangled states and entanglement between continuous properties are valuable resources for quantum information, but are notoriously difficult to generate. An experiment now entangles
Experimental verification of multipartite entanglement in quantum networks
TLDR
A protocol is designed and experimentally demonstrated that allows any party in a network to check if a source is distributing a genuinely multipartite entangled state, even in the presence of untrusted parties, and remains secure against dishonest behaviour of the source and other parties.
