Information-disturbance tradeoff in sending Direction information via antiparallel quantum spin
ShengLi Zhang, XuBo Zou, ChuanFeng Li +2
For sending unknown direction information, antiparallel spins contains more direction information than parallel spins(Gisin and Popescu, 1999, \textit{Phys. Rev. Lett.} 83, 432).In…

Multipartite continuous-variable entanglement distillation using local squeezing and only one photon-subtraction operation
Song Yang, XuBo Zou, ShengLi Zhang +3
In this paper, we study entanglement distillation of multipartite continuous-variable Gaussian entangled states. Following Opatrný \emph{et al.}'s photon subtraction (PS) scheme, t…

Local Gaussian operations can enhance continuous-variable entanglement distillation
ShengLi Zhang, Peter van Loock
Entanglement distillation is a fundamental building block in long-distance quantum communication. Though known to be useless on their own for distilling Gaussian entangled states,…
