    "abstract": "We consider the problem of obtaining maximally entangled photon states at\ndistance in the presence of loss. We compare the efficiency of two different\nschemes in establishing $N$ shared ebits: i) $N$ single ebit states with the\nqubit encoded on polarization; ii) a single continuous variable entangled state\n(emode) assisted by optimal local operation and classical communication (LOCC)\nprotocol in order to obtain a $2^N$-dimensional maximally entangled state, with\nqubits encoded on the photon number.",
