%X In this paper, we promote a principle of polarization feedback which keeps polarization states stable in long-distance fiber. It is quite difficult to realize long-term stable quantum key distribution (QKD) with polarization encoding due to the effect of irregular polarization fluctuation in single mode fiber. We have designed a polarization feedback control system to compensate for the birefringence. And a polarization encoded QKD experiment has been realized in 100km fiber.
