    "abstract": "We propose an auto-compensating differential phase shift scheme for quantum\nkey distribution with a high key-creation efficiency, which skillfully makes\nuse of automatic alignment of the photon polarization states in optical fiber\nwith modified Michelson interferometers composed of unequal arms with Faraday\nmirrors at the ends. The Faraday-mirrors-based Michelson interferometers not\nonly function as pulse splitters, but also enable inherent compensation of\npolarization mode dispersion in the optic-fiber paths at both Alice\u0027s and Bob\u0027s\nsites. The sequential pulses encoded by differential phase shifts pass through\nthe quantum channel with the same polarization states, resulting in a stable\nkey distribution immune to the polarization mode dispersion in the quantum\nchannel. Such a system features perfect stability and higher key creation\nefficiency over traditional schemes.",
