Complete Hierarchies for the Geometric Measure of Entanglement
Lisa T. Weinbrenner, Albert Rico, Kenneth Goodenough +2
In quantum physics, multiparticle systems are described by quantum states acting on tensor products of Hilbert spaces. This product structure leads to the distinction between produ…
Scalable Certification of Entanglement in Quantum Networks
Jing-Tao Qiu, D. M. Tong, Xiao-Dong Yu
Quantum networks form the backbone of long-distance quantum information processing. Genuine multipartite entanglement (GME) serves as a key indicator of network performance and ove…
Virtual Cloning of Quantum States
Zhi-Hao Bi, Jing-Tao Qiu, Xiao-Dong Yu
The inherent limitations of physical processes prevent the copying of arbitrary quantum states. Furthermore, even if we only aim to clone two distinct quantum states, it remains im…
Superactivation and Incompressibility of Genuine Multipartite Entanglement
Lisa T. Weinbrenner, Klára Baksová, Sophia Denker +4
Quantum correlations in the form of entanglement, quantum steering or Bell nonlocality are resources for various information-processing tasks, but their detailed quantification and…
Protecting entanglement witnesses with randomized measurements
Jing-Tao Qiu, Wei-Jie Jiang, Xiao-Dong Yu
Entanglement is one of the most prominent features of quantum mechanics and serves as an essential resource in quantum information science. Therefore, the certification of entangle…
