Sending-or-Not-Sending with Independent Lasers: Secure Twin-Field Quantum Key Distribution Over 509 km
Jiu-Peng Chen, Chi Zhang, Yang Liu +15
Twin field quantum key distribution promises high key rates at long distance to beat the rate distance limit. Here, applying the sending or not sending TF QKD protocol, we experime…
General sending-or-not-sending twin field protocol for quantum key distribution with asymmetric source parameters
Xiao-Long Hu, Cong Jiang, Zong-Wen Yu +1
The sending-or-not-sending (SNS) protocol of the twin-field quantum key distribution (TFQKD) can tolerant large misalignment error and its key rate can exceed the bound of repeater…
Zigzag approach to higher key rate of sending-or-not-sending twin field quantum key distribution with finite key effects
Cong Jiang, Xiao-Long Hu, Hai Xu +2
Odd-parity error rejection (OPER) can drastically improve the asymptotic key rate of sending-or-not-sending twin-field (SNS-TF) quantum key distribution (QKD). However, in practice…
Unconditional security of sending or not sending twin-field quantum key distribution with finite pulses
Cong Jiang, Zong-Wen Yu, Xiao-Long Hu +1
The Sending-or-Not-Sending protocol of the twin-field quantum key distribution (TF-QKD) has its advantage of unconditional security proof under any coherent attack and fault tolera…
Guessing probability in quantum key distribution
Xiang-Bin Wang, Jing-Tao Wang, Ji-Qian Qin +2
On the basis of the existing trace distance result, we present a simple and efficient method to tighten the upper bound of the guessing probability. The guessing probability of the…
Improved results for sending-or-not-sending twin-field quantun key distribution: breaking the absolute limit of repeaterless key rate
Hai Xu, Zong-Wen Yu, Cong Jiang +2
We present improved method of sending-or-not-sending twin-field quantum key distribution (SNS TF-QKD) based on its structure and the application of error rejection. %And we present…
