Abstract

We have studied experimentally the effect of a depolarizing quantum channel on polarization-encode weak pulse BB84 and SARG04 quantum cryptography. Experimental results show that, in real world conditions in which channel depolarization cannot be ignored, BB84 is more robust than SARG04 on the effect of the depolarizing quantum channel.
