| Experimental mode-pairing quantum key distribution surpassing the repeaterless bound | QCRYPT 2025 | regular | Likang Zhang, Wei Li, Jiawei Pan, Yichen Lu, Wenwen Li, Yizhi Huang, Xiongfeng Ma, Feihu Xu, Jianwei Pan |
We demonstrate a practical high-performance mode-pairing quantum key distribution system that is able to surpass the repeaterless key rate bound using commercial lasers. We propose a frequency tracking scheme to address phase fluctuations and a theoretical model to analyze the phase noise and optimize the system parameters. Our system achieves a secret key rate of 47.8 bit/s over 403 km standard fiber, which is 2.92 times of the repeaterless bound. Furthermore, we compare the performance between MP-QKD and no-phase-locking TF-QKD under various practical conditions and show that MP-QKD exhibits superior performance at short distances with low error rates, while TF-QKD is more advantageous for long distances with consistent error rates. |
