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…

Covariant feedback Control of arbitrary qudit state against Depolarizing Noise is impossible
ShengLi Zhang, XuBo Zou, Chuanfeng Li +2
In this paper, we prove that it is impossible to construct a convariant quantum feedback control instruments which aim to correct the channel noise imposed on an unknown qubit. The…

Closing the gap of secure quantum key rate with the Heralded Pair-Coherent States
ShengLi Zhang, XuBo Zou, ChenHui Jin +1
In this paper, we investigate the long-standing gap of quantum key rate between the Weak Coherent Pulse (WCP) and Heralded Single Photon Sources(HSPS) implementation of quantum cry…
