چکیده انگلیسی:
Private and secure communication is an indispensable
part of the government and individual activities. With the everevolving large-scale of quantum computing, traditional public-key
cryptography is severely threatened since its security only relies
on the computational complexity of certain mathematical functions. Quantum key distribution (QKD), ascribed to its security
based on the inviolability of physics laws, provides an absolutely
information-secure solution for the future extensive communication encrypting. Herein this Letter, we proposed a simplified and
reconfigurable silicon photonics encoder using a pass-block architecture and experimentally demonstrated its performance with a
specialized silicon photonics decoder for high-speed quantum key
distribution in polarization-based decoy-state BB84 protocol. We
achieved an estimated asymptotic secret key rate of 868 kbps with
measured quantum bit error rate (QBER) of 0.90% (Z base) and
1.34% (X base) over 20 km emulated fiber link. This work further
advances the process of applying QKD using silicon photonics
devices into the future secure telecommunication network.
