    "abstract": "We propose a quantum transmission based on bi-photons which are\ndoubly-entangled both in polarisation and phase. This scheme finds a natural\napplication in quantum cryptography, where we show that an eventual\neavesdropper is bound to introduce a larger error on the quantum communication\nthan for a single entangled bi-photon communication, when steeling the same\ninformation.",
