    "abstract": "We present a scheme to realize a quantum key distribution using vacuum-one\nphoton entangled states created both from Alice and Bob. The protocol consists\nin an exchange of spatial modes between Alice and Bob and in a recombination\nwhich allows one of them to reconstruct the bit encoded by the counterpart in\nthe phase of the entangled state. The security of the scheme is analyzed\nagainst some simple kind of attack. The model is shown to reach higher\nefficiency with respect to prior schemes using phase encoding methods.",
