On Ergotropic Gap of Tripartite Separable Systems
Ya-Juan Wu, Shao-Ming Fei, Zhi-Xi Wang +1
Extracting work from quantum system is one of the important areas in quantum thermodynamics. As a significant thermodynamic quantity, the ergotropy gap characterizes the difference…
A Complete Set of Local Invariants for a Family of Multipartite Mixed States
Xiao-Hong Wang, Shao-Ming Fei, Ke Wu
We study the equivalence of quantum states under local unitary transformations by using the singular value decomposition. A complete set of invariants under local unitary transform…
Entanglement conditions for multi-mode states
Zong-Guo Li, Shao-Ming Fei, Zhi-Xi Wang +1
We provide a class of inequalities for detecting entanglements in multi-mode systems. Necessary conditions for fully separable, bi-separable and sufficient conditions for fully ent…
Lower Bounds of Concurrence for Tripartite Quantum Systems
Xiu-Hong Gao, Shao-Ming Fei, Ke Wu
We derive an analytical lower bound for the concurrence of tripartite quantum mixed states. A functional relation is established relating concurrence and the generalized partial tr…
On PPT States in KxMxN Composite Quantum Systems
Xiao-Hong Wang, Shao-Ming Fei, Zhi-Xi Wang +1
We study the general representations of positive partial transpose (PPT) states in . For the PPT states with rank- a canonical…
Canonical Form and Separability of PPT States in 2xMxN Composite Quantum Systems
X. H. Wang, S. M. Fei, Z. X. Wang +1
We investigate the canonical forms of positive partial transposition (PPT) density matrices in composite quantum systems with ran…
