Decidabilities of local unitary equivalence for entanglement witnesses and states
Yi Shen, Lin Chen
The problem of determining whether two states are equivalent by local unitary (LU) operations is important for quantum information processing. In this paper we propose an alternati…
An experimental proposal certification for any three-qubit generalized Greenberger-Horne-Zeilinger states based on the fine-grained steering inequality
Zhi-Hao Bian, Jia-Qi Sun, Yi Shen
Multi-party quantum steering is an important concept in quantum information theory and quantum mechanics, typically related to quantum entanglement and quantum nonlocality. It enab…
The detection power of real entanglement witnesses under local unitary equivalence
Yi Shen, Lin Chen, Zhihao Bian
The imaginary unit has recently been experimentally proven to be indispensable for quantum mechanics. We study the differences in detection power between real and complex entan…
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…
The additivity of states uniquely determined by marginals
Yi Shen, Lin Chen
The pure states that can be uniquely determined among all (UDA) states by their marginals are essential to efficient quantum state tomography. We generalize the UDA states from the…
Inertia of two-qutrit entanglement witnesses
Changchun Feng, Lin Chen, Chang Xu +1
Entanglement witnesses (EWs) are a fundamental tool for the detection of entanglement. We investigate the inertias of bipartite EWs constructed by the partial transpose of NPT stat…
