Observation impact in data assimilation: the effect of non-Gaussian observation error [PDF]
Tellus: Series A, Dynamic Meteorology and Oceanography, 2013 Data assimilation methods which avoid the assumption of Gaussian error statistics are being developed for geoscience applications. We investigate how the relaxation of the Gaussian assumption affects the impact observations have within the assimilation ...

Nihon Kikai Gakkai ronbunshu, 2015 Equivalent non-Gaussian excitation method is developed to obtain the statistical moments up to 4th order of the response of non-Gaussian randomly excited systems. The non-Gaussian excitation is prescribed by the probability density function and the power

Classical simulation of Gaussian quantum circuits with non-Gaussian input states
Physical Review Research, 2021 We consider Gaussian quantum circuits supplemented with non-Gaussian input states and derive sufficient conditions for efficient classical strong simulation of these circuits. In particular, we generalise the stellar representation of continuous-variable

Physical Review Research, 2021 Gaussian states and measurements collectively are not powerful-enough resources for quantum computing, as any Gaussian dynamics can be simulated efficiently, classically.

Non-Gaussian Quantum States and Where to Find Them
PRX Quantum, 2021 Gaussian states have played an important role in the physics of continuous-variable quantum systems. They are appealing for the experimental ease with which they can be produced, and for their compact and elegant mathematical description.

SVM Based on Gaussian and Non-Gaussian Double Subspace for Fault Detection
IEEE Access, 2021 In industrial production processes, the data usually have high-dimensional characteristics. When a support vector machine (SVM) is used for fault detection, it takes a long time to run.

Hierarchy of continuous-variable quantum resource theories
New Journal of Physics, 2021 Connections between the resource theories of coherence and purity (or non-uniformity) are well known for discrete-variable, finite-dimensional, quantum systems.
