A characterization of entangled two-qubit states via partial-transpose-moments
Lin Zhang, Ming-Jing Zhao, Lin Chen +2
Although quantum entanglement is an important resource, its characterization is quite challenging. The partial transposition is a common method to detect bipartite entanglement. In…

Multipartite Entanglement Measure and Complete Monogamy Relation
Yu Guo, Lin Zhang
Although many different entanglement measures have been proposed so far, much less is known in the multipartite case, which leads to the previous monogamy relations in literatures…

Fidelity between a bipartite state and another one undergoing local unitary dynamics
Lin Zhang, Lin Chen, Kaifeng Bu
The fidelity and local unitary transformation are two widely useful notions in quantum physics. We study two constrained optimization problems in terms of the maximal and minimal f…
