Characterizing High Schmidt Number Witnesses in Arbitrary Dimensions System
Liang Xiong, Nung-sing Sze
A profound comprehension of quantum entanglement is crucial for the progression of quantum technologies. The degree of entanglement can be assessed by enumerating the entangled deg…
Criteria of absolutely separability from spectrum for qudit-qudits states
Liang Xiong, Nung-Sing Sze
Separability from the spectrum is a significant and ongoing research topic in quantum entanglement. In this study, we investigate properties related to absolute separability from t…
Observing geometry of quantum states in a three-level system
Jie Xie, Aonan Zhang, Ningping Cao +7
In quantum mechanics, geometry has been demonstrated as a useful tool for inferring non-classical behaviors and exotic properties of quantum systems. One standard approach to illus…
Criteria and new classes of k-positive maps
Jinchuan Hou, Chi-Kwong Li, Yiu-Tung Poon +2
We study k-positive maps on operators. Proofs are given to different positivity criteria. Special attention is on positive maps arising in the study of quantum information science.…
Linear preservers and quantum information science
Ajda Fosner, Zejun Huang, Chi-Kwong Li +1
Let be positive integers, the set of complex matrices and the set of complex matrices. Regard as the tensor space $M_m\otime…
