| Abstract: | We report experimental studies on the effect of the depolarizing quantum channel on weak-pulse BB84 and SARG04 quantum cryptography.
The experimental results show that, in real world conditions in which channel depolarization cannot be ignored, BB84 should
perform better than SARG04 under the most general eavesdropping attack. |
