Transfer of a polaritonic qubit through a coupled cavity arrayTransfer of a polaritonic qubit through a coupled cavity array Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-222007enWe demonstrate a scheme for quantum communication between the ends of an array of coupled cavities. Each cavity is doped with a single two level system (atoms or quantum dots) and the detuning of the atomic level spacing and photonic frequency is appropriately tuned to achieve photon blockade in the array. We show that in such a regime, the array can simulate a dual rail quantum state transfer protocol where the arrival of quantum information at the receiving cavity is heralded through a fluorescence measurement. Communication is also possible between any pair of cavities of a network of connected cavities.http://creativecommons.org/licenses/by/4.0/Journal of Modern Optics5413-152307-2314 Bose Sougato Aggelakis Dimitrios Αγγελακης Δημητριος Burgarth Daniel Taylor & Francis Coupled cavities Polaritonic qubit
