ABSTRACT
We propose a “plug and play” scheme for the long-distance fiber-based cryptosystem based on the differential phase shift quantum key distribution, where any birefringence effects and polarization-dependent losses in the transmission fiber are automatically compensated by using a Faraday mirror. This system not only has stable performance but also creates keys 8/3 times more efficiently than the conventional cryptosystem based on the BB84 protocol. © 2003 American Institute of Physics.

    We have investigated the dependence of the photoinduced birefringence in a low-molecular azopolymer on the exciting light intensity at elevated temperatures. We have found that in the temperature range 44–56 °C the stationary photobirefringence is higher for a low pump intensity(1 mW)...
