Exploring the potential of hybrid two-qubit solid-state nodes for quantum networks
ORAL
Abstract
We demonstrate an elementary quantum network consisting of a pair of hybrid two-qubit quantum nodes. These nodes combine nitrogen-vacancy defects in diamond as spin-photon interfaces for entanglement generation, state manipulation and measurement along with coupled carbon nuclear-spin quantum memories. We utilise this network to investigate different quantum information protocols for establishing links over few-qubit quantum networks in the near term. We find that the ability to coherently store quantum information during attempts to generate network links may increase the rate at which entanglement can be generated.
