Convexity and non-Markovianity of Weyl Maps
Wen Xu, Vinayak Jagadish
We investigate the emergence of non-Markovian dynamics in finite-dimensional open quantum systems governed by Weyl dynamical maps and their convex combinations. Using the Hermite n…
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…
Witnessing quantum coherence with prior knowledge of observables
Mao-Sheng Li, Wen Xu, Shao-Ming Fei +2
Quantum coherence is the key resource in quantum technologies including faster computing, secure communication and advanced sensing. Its quantification and detection are, therefore…
Beyond the mixture of generalized Pauli dephasing channels
Mao-Sheng Li, Wen Xu, Yan-Ling Wang +1
In recent times, there has been a growing scholarly focus on investigating the intricacies of quantum channel mixing. It has been commonly believed, based on intuition in the liter…
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…
