Einstein-Podolsky-Rosen steering criterion and monogamy relation via correlation matrices in tripartite systems
Quantum steering is considered one of the most well-known nonlocal phenomena in
quantum mechanics. Unlike entanglement and Bell nonlocality, the asymmetry of quantum …

Comparing metrics for mixed quantum states: Sjöqvist and Bures
It is known that there are infinitely many distinguishability metrics for mixed quantum states.
This freedom, in turn, leads to metric-dependent interpretations of physically meaningful …

Negativity vs. purity and entropy in witnessing entanglement
In this paper, we explore the value of measures of mixedness in witnessing entanglement.
While all measures of mixedness may be used to witness entanglement, we show that all …

Numerical evidence for a bipartite pure state entanglement witness from approximate analytical diagonalization
PM Alsing, RJ Birrittella - arXiv preprint arXiv:2404.13725, 2024 - arxiv.org
We show numerical evidence for a bipartite $ d\times d $ pure state entanglement witness
