    "abstract": "We give an entanglement assisted scheme for quantum key distribution.\n  The scheme requires the maximally entangled 2-qubit state but does not\nrequire any quantum storage. The scheme is unconditionally secure under\nwhatever Eve\u0027s attack.\n  Given the symmetric noisy channel with uncorrelated noise, our scheme can\ntolerate the bit error rate up to\n  26% in the 4-state case and 30% in the\n  6-state respectively, respectively. These values are higher than those of all\ncurrently known two-level-state schemes without using a quantum storage.",
