Sending-or-Not-Sending Twin-Field Quantum Key Distribution with Redundant Space
Hai Xu, Xiao-Long Hu, Cong Jiang +2
We propose to adopt redundant space such as polarization mode in the sending-or-not-sending Twin-Field quantum key distribution (TF-QKD) in the Fock space. With the help of redunda…
Optomechanical dynamics in the - and broken--symmetric regimes
Hai Xu, Deng-Gao Lai, Yi-Bing Qian +3
We theoretically study the dynamics of typical optomechanical systems, consisting of a passive optical mode and an active mechanical mode, in the - and broken-$\mathc…
Field Test of Twin-Field Quantum Key Distribution through Sending-or-Not-Sending over 428 km
Hui Liu, Cong Jiang, Hao-Tao Zhu +18
Quantum key distribution endows people with information-theoretical security in communications. Twin-field quantum key distribution (TF-QKD) has attracted considerable attention be…
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…
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…
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…
