Multipartite entanglement distribution using separable states

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Entanglement distribution among the nodes of a quantum network is possible without having to send any entanglement. We extend this phenomenon to a multipartite setting, using one separable carrier to entangle multiple qubits. It is shown that postselective measurements on the carrier at the end of the protocol can be used to enhance the entanglement produced. We consider the impact of sending the carrier through noisy channels. An experimental proposal is put forward to demonstrate how this could be realised using photons.
