Computable genuine multimode entanglement measure: Gaussian versus non-Gaussian [PDF]

open access: yesPhysical Review A, 2020
Genuine multimode entanglement in continuous variable systems can be quantified by exploring the geometry of the state-space, namely via the generalized geometric measure (GGM) which is defined as the shortest distance of a given multimode state from a nongenunely multimode entangled state.

SOLUTION TO A PARABOLIC DIFFERENTIAL EQUATION IN HILBERT SPACE VIA FEYNMAN FORMULA I

open access: yesМоделирование и анализ информационных систем, 2015
A parabolic partial differential equation u′t (t, x) = Lu(t, x) is considered, where L is a linear second-order differential operator with time-independent coefficients, which may depend on x. We assume that the spatial coordinate x belongs to a finiteor

Measure of Similarity between GMMs Based on Autoencoder-Generated Gaussian Component Representations

open access: yesAxioms, 2023
A novel similarity measure between Gaussian mixture models (GMMs), based on similarities between the low-dimensional representations of individual GMM components and obtained using deep autoencoder architectures, is proposed in this paper.

On relation between one multiple and a corresponding one-dimensional integral with applications [PDF]

open access: yesYugoslav Journal of Operations Research, 2018
For a given finite positive measure on an interval I ⊆ R, a multiple stochastic integral of a Volterra kernel with respect to a product of a corresponding Gaussian orthogonal stochastic measure is introduced.

Gromov’s Waist of Non-radial Gaussian Measures and Radial Non-Gaussian Measures [PDF]

open access: yes, 2020
We study the Gromov waist in the sense of $t$-neighborhoods for measures in the Euclidean space, motivated by the famous theorem of Gromov about the waist of radially symmetric Gaussian measures. In particular, it turns our possible to extend Gromov's original result to the case of not necessarily radially symmetric Gaussian measure.

Nonclassicality by Local Gaussian Unitary Operations for Gaussian States

open access: yesEntropy, 2018
A measure of nonclassicality N in terms of local Gaussian unitary operations for bipartite Gaussian states is introduced. N is a faithful quantum correlation measure for Gaussian states as product states have no such correlation and every non

Quantum steering of Gaussian states via non-Gaussian measurements [PDF]

open access: yesScientific Reports, 2016
AbstractQuantum steering—a strong correlation to be verified even when one party or its measuring device is fully untrusted—not only provides a profound insight into quantum physics but also offers a crucial basis for practical applications. For continuous-variable (CV) systems, Gaussian states among others have been extensively studied, however ...

Image illumination enhancement with an objective no-reference measure of illumination assessment based on Gaussian distribution mapping

open access: yesEngineering Science and Technology, an International Journal, 2015
Illumination problems have been an important concern in many image processing applications. The pattern of the histogram on an image introduces meaningful features; hence within the process of illumination enhancement, it is important not to destroy such

Estimating Non-Gaussianity of a Quantum State by Measuring Orthogonal Quadratures

open access: yesEntropy, 2022
We derive the lower bounds for a non-Gaussianity measure based on quantum relative entropy (QRE). Our approach draws on the observation that the QRE-based non-Gaussianity measure of a single-mode quantum state is lower bounded by a function of the ...
