- Abstract summary: We develop a strategy for entanglement distribution via separable carriers that can be applied to any number of network nodes.
We show that our protocol results in multipartite entanglement, while the carrier mediating the process is always in a separable state with respect to the network.

- Abstract: The ability to reliably distribute entanglement among the nodes of a network
is an essential requirement for the development of effective quantum
communication protocols and the realization of useful quantum networks. It has
been demonstrated, in different contexts, that two remote systems can be
entangled via local interactions with a carrier system that always remains in a
separable state with respect to such distant particles. We develop a strategy
for entanglement distribution via separable carriers that can be applied to any
number of network nodes to achieve various entanglement distribution patterns.
We show that our protocol results in multipartite entanglement, while the
carrier mediating the process is always in a separable state with respect to
the network. We provide examples showcasing the flexibility of our approach and
propose a scheme of principle for the experimental demonstration of the
protocol.
