Steady-state entanglement between hybrid light-matter qubitsSteady-state entanglement between hybrid light-matter qubits Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-212009enWe study the case of two polaritonic qubits localized in two separate cavities coupled by a fiber/additional cavity. We show that classical driving of the intermediate cavity/fiber can lead to the creation of entanglement between the two ends in the steady state. The stationary nature of this entanglement and its survival under dissipation opens possibilities for its production under realistic laboratory conditions. To facilitate the verification of the entanglement in an experiment we also construct the relevant entanglement witness measurable by accessing only a few local variables of each polaritonic qubit.http://creativecommons.org/licenses/by/4.0/EPL852 Aggelakis Dimitrios Αγγελακης Δημητριος Mancini Stefano Bose Sougato IOP Publishing Steady entanglement
