- Abstract: Entanglement is an essential ingredient for building a quantum network that
can have many applications. Understanding how entanglement is distributed in a
network is a crucial step to move forward. Here we study the conservation and
distribution of Gaussian entanglement in a linear network using a new
quantifier for bipartite entanglement. We show that the entanglement can be
distributed through a beam-splitter in the same way as the transmittance and
the reflectance. The requirements on the entangled states and the type of
networks to satisfy this relation are presented explicitly. Our results provide
a new quantification for quantum entanglement and further insights into the
structure of entanglement in a network.

We show that the most well-known network Bell test does not witness full network nonlocality.
More generally, we point out that established methods for analysing local and theory-independent correlations in networks can be combined in order to deduce sufficient conditions for full network nonlocality.
