Hybrid Quantum Noise Model to Compute Gaussian Quantum Channel Capacity

IEEE Access
Quantum information processing leverages the principles of quantum mechanics, utilizing qubits, to improve computational and communicative tasks. In this realm, the quantum channel’s capacity is pivotal in determining the efficiency and accuracy ...

On the Role of Non-Gaussian Noises on Noise-Induced Phenomena [PDF]

, 2004
Most of the studies of noise-induced phenomena assume that the noise source is Gaussian (either white or colored). Here we present recent results of some of those noise-induced phenomena when driven by a noise source taken as colored and non-Gaussian, generated by a nonextensive g-distribution.

Image reconstruction under non-Gaussian noise [PDF]

, 2017
During acquisition and transmission, images are often blurred and corrupted by noise. One of the fundamental tasks of image processing is to reconstruct the clean image from a degraded version. The process of recovering the original image from the data is an example of inverse problem.

A novel robust interacting multiple model filter for manoeuvering target tracking

Electronics Letters
A robust interacting multiple model approach is proposed to address the problem of accuracy and non‐Gaussian measurement noise in manoeuvering target tracking. The proposed approach introduces multiple fading factors into the prediction covariance matrix

Gravitational wave non-Gaussianity from trans-Planckian quantum noise

Journal of Cosmology and Astroparticle Physics
Abstract We examine the effect of a trans-Planckian phase on the dynamics of inflationary tensor perturbations. To remedy the fact that this regime is not fully captured by standard perturbation theory, we introduce an effective quantum noise source, whose role is regulated by the energy scale Λ. The presence of the source modifies

Student’s t-Kernel-Based Graph Signals Maximum Correntropy Unscented Kalman Filter Under Hybrid Cyberattacks

IET Signal Processing
The implementation of Kalman filter (KF) in tracking high-dimensional, strongly correlated graph structured data is often complex and unstable. Meanwhile, in practical applications, the system may be subject to interference from non-Gaussian noise and ...

Weak universality of dynamical $\Phi^4_3$: non-Gaussian noise

, 2016
We consider a class of continuous phase coexistence models in three spatial dimensions. The fluctuations are driven by symmetric stationary random fields with sufficient integrability and mixing conditions, but not necessarily Gaussian. We show that, in the weakly nonlinear regime, if the external potential is a symmetric polynomial and a certain ...

Extended Object Tracking Based on Gaussian Process in Non-Gaussian Noise Environment

Journal of Aerospace Technology and Management
Extended object tracking (EOT) is a prominent research area in high-resolution radar surveillance, ship tracking, and video tracking. However, EOT algorithms are susceptible to non-Gaussian noise from factors such as sensor performance and ...
