    "abstract": "A one-way quantum key distribution scheme based on intrinsically stable\nFaraday-mirror type Michelson interferometers with four-port polarizing\nbeampslitters has been demonstrated which can compensate for birefringence\neffects automatically. The encoding is performed with phase modulators, but\ndecoding is accomplished through measurement of the polarization state of Bob\u0027s\nphotons. An extinction ratio of about 30dB was maintained for several hours\nover 50km of fiber at 1310nm without any adjustment to the setup, which shows\nits good potential for practical systems",
