We have improved the hardware and software of our autocompensating system for quantum key distribution by replacing bulk optical components at the end stations with fiber-optic equivalents and implementing software that synchronizes end-station activities, communicates basis choices, corrects errors, and performs privacy amplification over a local area(More)
A new method for measuring the backscattering produced by mirrors is presented. A mode-locked ring laser allows us to achieve more sensitivity than with any other technique. The present sensitivity to a minimum intensity backscattering coefficient (ratio of backscattered versus incident intensity) of 10(-15) can be enhanced through stabilization. We compare(More)
