Area-Law Entanglement in Quantum Chaotic System
Chunyin Chen, Sizhe Yan, Biao Wu
Entanglement entropy is a fundamental diagnostic for quantum chaos, typically exhibiting volume-law scaling in highly excited eigenstates of chaotic many-body systems. In this work…

Incorporating Zero-Probability Constraints to Device-Independent Randomness Expansion
Chun-Yu Chen, Kai-Siang Chen, Kai-Min Chung +3
One of the distinguishing features of quantum theory is that its measurement outcomes are usually unpredictable or, equivalently, random. Moreover, this randomness is certifiable w…
