Spectral bounds for the partial transpose
Wei-Jie Jiang, Jing-Tao Qiu, Xiao-Dong Yu
Among the various entanglement measures, the negativity stands out not only for its clear physical meaning but also for being directly computable from the spectrum of the partial t…
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…
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…
Strict hierarchy of optimal strategies for global estimations: Linking global estimations with local ones
Zhao-Yi Zhou, Jing-Tao Qiu, Da-Jian Zhang
A crucial yet challenging issue in quantum metrology is to ascertain the ultimate precision achievable in estimation strategies. While there are two paradigms of estimations, local…
