WebAug 13, 2024 · Abstract Non-Gaussianity is an important resource for quantum information processing with continuous variables. We introduce a measure of the non-Gaussianity of bosonic field states based on the Hellinger distance and present its basic features. This measure has some natural properties and is easy to compute. We illustrate this measure … WebJan 1, 2013 · The preceding discussion suggests that the empirical features of aggregational Gaussianity and infinite variance of financial returns can coincide due to the limit theorems for mixing sequences with barely infinite variance.
