Quantum Tunneling: From Theory to Error‐Mitigated Quantum Simulation

Advanced Quantum Technologies, Volume 8, Issue 1, January 2025.
Quantum simulations are regarded as a promising undertaking in the field of quantum computing. This study focuses on quantum tunneling and aims at simulating it on a quantum computer. With a focus on hardware run considerations for superconducting architectures, various circuit implementation alternatives are clarified.

Confidence Intervals in High-Dimensional Regression Based on Regularized Pseudoinverses

, 2017
In modern data sets, the number of available variables can greatly exceed the number of observations. In this paper we show how valid confidence intervals can be constructed by approximating the inverse covariance matrix by a scaled Moore-Penrose ...

Terminal value problem for the system of fractional differential equations with additional restrictions

Mathematical Modelling and Analysis
This paper deals with the study of terminal value problem for the system of fractional differential equations with Caputo derivative. Additional conditions are imposed on the solutions of this problem in the form of a linear vector functional. Using the

Kalman Filtering with Unknown Noise Covariances [PDF]

, 2006
Since it is often difficult to identify the noise covariances for a Kalman filter, they are commonly considered design variables. If so, we can as well try to choose them so that the corresponding Kalman filter has some nice form.

COMPUTATIONAL ALGORITHM FOR AN MP3 (MOORE-PENROSE 3) MATRIX RING AND FORMULATION OF MP3 EQUIVALENCE

, 2014
The structure theorems for complete local rings are largely due to Irving S. Cohen. The beginning part of Cohen's structure theorem for the equicharacteristic case is "A complete local ring which has the same characteristic as its residue field contains ...

Sketch-based Randomized Algorithms for Dynamic Graph Regression

, 2019
A well-known problem in data science and machine learning is {\em linear regression}, which is recently extended to dynamic graphs. Existing exact algorithms for updating the solution of dynamic graph regression problem require at least a linear time (in

Constrained trajectory optimization for kinematically redundant arms [PDF]

Two velocity optimization schemes for resolving redundant joint configurations are compared. The Extended Moore-Penrose Technique minimizes the joint velocities and avoids obstacles indirectly by adjoining a cost gradient to the solution.
