- Abstract
- SARG04 uses the same quantum states and the same measurement bases with BB84 protocol, but SARG04 can generate secret keys from two-photon pulses when BB84 cannot. We report the implementation of BB84 and SARG04 protocols using a polarization-encoded weak coherent pulse with an optical fiber quantum channel. We have experimentally investigated the secret key rate of BB84 and SARG04 protocols, and BB84 gave a higher secret key rate than SARG04.
