Power and Limits of Collective Local Measurements in Multicopy State Discrimination
Mao-Sheng Li, Yan-Ling Wang, Zhu-Jun Zheng
More than two decades ago, Bennett \emph{et al.} [Phys. Rev. A \textbf{59}, 1070 (1999)] asked whether perfect local discrimination of orthogonal quantum states can require more th…
Inclusion-Minimal local indistinguishability: a weak form of nonlocality
Mao-Sheng Li, Zong-Xing Xiong, Zhu-Jun Zheng +1
Local discrimination of quantum states is a fundamental task in distributed quantum information processing and underlies applications such as quantum communication, data hiding, an…
Simultaneous Detection of High-Dimensional Entanglement for Two Unknown Quantum States
Mao-Sheng Li, Chang-Yue Zhang, Zheng Zheng +7
The state overlap, quantified via $\tr[ρσ]$, is a metric widely used to assess the closeness between two quantum states and . Although global state overlap alone does not di…
A Dynamical Lie-Algebraic Framework for Hamiltonian Engineering and Quantum Control
Yanying Liang, Ruibin Xu, Mao-Sheng Li +2
Determining the unitary dynamics accessible from finite Hamiltonian resources is a central problem in Hamiltonian engineering and quantum control. Dynamical Lie algebras (DLAs) con…
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…
