    "abstract": "We present a new fiber based quantum key distribution (QKD) scheme which can\nbe regarded as a modification of an idea proposed by Inoue, Waks and Yamamoto\n(IWY) [1]. The scheme described here uses a single phase modulator and two\ndifferential delay elements in series at the transmitter that form an\ninterferometer when combined with a third differential delay element at the\nreceiver. The protocol is characterized by a high efficiency, reduced exposure\nto an attack by an eavesdropper, and higher sensitivity to such an attack when\ncompared to other QKD schemes. For example, the efficiency with which\ntransmitted data contribute to the private key is 3/4 compared with 1/4 for\nBB84 [2]. Moreover, an eavesdropper can aquire a maximum of 1/3 of the key\nwhich leads to an error probability in the private key of 1/3. This can be\ncompared to 1/2 and 1/4 for these same parameters in both BB84 and IWY. The\ncombination of these considerations should lead to increased range and key\ndistribution rate over present fiber-based QKD schemes.",
