Creation of 2000-atom Greenberger-Horne-Zeilinger states by entanglement amplification
Yajuan Zhao, Rui Zhang, Wenlan Chen +2
We propose a novel entanglement-creation scheme in a multi-atom ensemble, named entanglement amplification, which converts unentangled states into entangled states and amplifies le…
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…
Experimental 4-intensity decoy-state quantum key distribution with asymmetric basis detector efficiency
Hui Liu, Zong-Wen Yu, Mi Zou +6
The decoy-state method has been developed rapidly in quantum key distribution (QKD) since it is immune to photon-number splitting attacks. However, two basis detector efficiency as…
Color Erasure Detectors Enable Chromatic Interferometry
Luo-Yuan Qu, Jordan Cotler, Fei Ma +7
By engineering and manipulating quantum entanglement between incoming photons and experimental apparatus, we construct single-photon detectors which cannot distinguish between phot…
