Mixed States Uniquely Determined by Marginals and Additivity
Xinyu Qiu, Lin Chen, Genwei Li +1
Identifying whether a mixed quantum state is uniquely determined among all states (UDA) by its local marginals is a basic problem in quantum information theory. We establish necess…

Machine Learning Framework for Efficient Prediction of Quantum Wasserstein Distance
Changchun Feng, Xinyu Qiu, Laifa Tao +1
The quantum Wasserstein distance (W-distance) is a fundamental metric for quantifying the distinguishability of quantum operations, with critical applications in quantum error corr…

Multipartite entangling power by von Neumann entropy
Xinyu Qiu, Zhiwei Song, Lin Chen
Quantifying the entanglement generation of a multipartite unitary operation is a key problem in quantum information processing. We introduce the definition of multipartite entangli…
