| Long-Distance Fiber Quantum Key Distribution using Wavelength-Multiplexed Entanglement | QCRYPT 2024 | Bo Li, Yixi Zeng, Yuhuai Li, Yuan Cao |
Fiber-based quantum key distribution (QKD) is a cornerstone technology for ensuring secure communication. Leveraging the spontaneous parametric down-conversion (SPDC) of periodically poled lithium niobate waveguide, we have generated a high-brightness and broad-band polarization-entangled photon source. By integrating this source with wavelength division multiplexing technology, we demonstrated an entanglement-based QKD experiment spanning over 400 km of optical fiber, marking a substantial advancement in extending distribution distances. This experiment represents a significant stride towards realizing future entanglement-based quantum networks. |
