Entanglement distillation on symmetric two-qutrit entangled states of rank five
Zihua Song, Lin Chen, Yongge Wang
Entanglement distillation is a key step in quantum information, both theoretically and practically. It has been proven that non-positive-partial transpose (NPT) entangled states of…
Virtual Quantum Markov Chain of four-qubit systems
Zhixing Chen, Lin Chen
We extend the framework of virtual quantum Markov chains (VQMCs) from tripartite systems to the four-qubit setting. Structural criteria such as the kernel-inclusion condition are a…
Spectral characterizations of entanglement witnesses
Zhiwei Song, Lin Chen
We present a systematic investigation of the spectral properties of entanglement witnesses (EWs). Specifically, we analyze the infimum and supremum of the largest eigenvalue, the s…
Equality condition for a matrix inequality by partial transpose
Nalan Wang, Lin Chen
The partial transpose map is a linear map widely used quantum information theory. We study the equality condition for a matrix inequality generated by partial transpose, namely $\r…
Unified Construction of Genuine Multipartite Entanglement Measures Based on Geometric Mean and its Applications
Zong Wang, Zhihao Ma, Lin Chen +2
Genuine multipartite entanglement (GME) is an important resource in quantum information processing. We systematically study the measures of GME based on the geometric mean of bi-pa…
Superadditivity of Convex Roof Coherence Measures in Multipartite System
Honglin Ren, Lin Chen
In this paper, we investigate the convex roof measure of quantum coherence, with a focus on their superadditive properties. We propose sufficient conditions and establish a framewo…
Commutators with multiple unitary symmetry
Shu Li, Jie Wang, Binfeng Wang +1
Commutators are essential in quantum information theory, influencing quantum state symmetries and information storage robustness. This paper systematically investigates the charact…
Non-Perturbative Geometric Framework for Single-Qubit Gates under Always-On Couplings
Junkai Zeng, Lin Chen, Xiu-Hao Deng
In qubit arrays with always-on couplings, single-qubit gates pose a control challenge often as demanding as entangling operations. The same interactions that enable two-qubit entan…
