Schmidt-number robustness as a unified quantifier of high dimensional entanglement in Buscemi nonlocality
Xian Shi
High-dimensional entanglement, captured by the Schmidt number, underpins advantages in quantum information tasks, yet a unified resource-theoretic description across different Busc…

Quantifying Coherence and Genuine Multipartite Entanglement : A Framework Based on Witness Operators and Frobenius Norm Distance
Mingyu Liu, Xian Shi
Quantifying the entanglement and coherence of quantum systems is a topic of significant theoretical and practical interest. In this paper, we propose a method to evaluate lower bou…

The Deimginarity Cost of Quantum States
Xian Shi
Here we address a task denoted as deimaginarity, which is to transform a state into a real state with the aid of random covariant-free unitary operations. We consider the minimum c…
