Exact Relation Between Wehrl-Rényi Entropy and Many-Body Entanglement
Pengfei Zhang, Chen Xu, Peng Zhang
Quantum entanglement is key to understanding correlations and emergent phenomena in quantum many-body systems. For qubits (distinguishable spin- particles) in a pure quant…

Bayesian Interpretation of Husimi Function and Wehrl Entropy
Chen Xu, Yiqi Yu, Peng Zhang
Husimi function (Q-function) of a quantum state is the distribution function of the density operator in the coherent state representation. It is widely used in theoretical research…
