A Fabry-Perot Microcavity for diamond based (NV) quantum information and communication processing — •Roland Nagy1, Sen Yang1, Helmut Fedder1, Durga Dasari1,2, and Jörg Wrachtrup1,2 — 13rd Institute of Physics and Research Center SCOPE, University of Stuttgart, Pfaffenwaldring 57, 70569 Stuttgart, Germany — 2Max Planck Institute for Solid State Research, Stuttgart
A high fidelity coupling of solid-state spins to microcavities opens up new prospectives for the field of quantum communications and quantum information processing. With applications towards photon memories, and entangled photon generation they could become key elements in quantum networks transporting quantum states and entanglement over long distances.
In this poster I will present a scheme to couple the electronic states of a Nitrogen Vacancy (NV) center in a thin diamond membrane to a Fabry-Perot cavity [1]. In the presence of a long-lived nuclear spin I will show how this system could become a robust hybrid device to store and entangle photons [2].
