Intrinsic randomness under general quantum measurements
Hao Dai, Boyang Chen, Xingjian Zhang +1
Quantum measurements can produce randomness arising from the uncertainty principle. When measuring a state with von Neumann measurements, the intrinsic randomness can be quantified…

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…
