The quantum non-Markovianity for a special class of generalized Weyl channel
Wen Xu, Mao-Sheng Li, Bo Li +2
A quantum channel is usually represented as a sum of Kraus operators. The recent study [Phys. Rev. A 98, 032328 (2018)] has shown that applying a perturbation to the Kraus operator…

Necessary conditions for classifying m-separability of multipartite entanglements
Wen Xu, Chuan-Jie Zhu, Zhu-Jun Zheng +1
We study the norms of the Bloch vectors for arbitrary -partite quantum states. A tight upper bound of the norms is derived for -partite systems with different individual dime…
