Renyi-alpha entropies of quantum states in closed form: Gaussian states and a class of non-Gaussian states

Ilki Kim

In this work, we study the Renyi-alpha entropies S_{alpha}(\hat{rho}) = (1 - alpha)^{-1} \ln{Tr(\hat{rho}^{alpha})} of quantum states for N bosons in the phase-space representation…
