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…
Phononic entanglement concentration via optomechanical interactions
Shan-Shan Chen, Hao Zhang, Qing Ai +1
Low dissipation, tunable coupling to other quantum systems, and unique features of phonons in the aspects of propagation, detection and others suggest the applications of quantized…
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…
A Full Quantum Eigensolver for Quantum Chemistry Simulations
Shijie Wei, Hang Li, GuiLu Long
Quantum simulation of quantum chemistry is one of the most compelling applications of quantum computing. It is of particular importance in areas ranging from materials science, bio…
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…
