Fundamental Limitation on the Detectability of Entanglement
Pengyu Liu, Zhenhuan Liu, Shu Chen +1
Entanglement detection is essential in quantum information science and quantum many-body physics. It has been proved that entanglement exists almost surely for a random quantum sta…

Dynamic quantum-enhanced sensing without entanglement in central spin systems
Wenkui Ding, Yanxia Liu, Zhenyu Zheng +1
We propose a dynamic quantum sensing scheme by using a quantum many-spin system composed of a central spin interacting with many surrounding spins. Starting from a generalized Isin…

Detecting entanglement in quantum many-body systems via permutation moments
Zhenhuan Liu, Yifan Tang, Hao Dai +3
Multipartite entanglement plays an essential role in both quantum information science and many-body physics. Due to the exponentially large dimension and complex geometric structur…
