The Quantum Eigenvalue Algorithm (QEA) is a quantum algorithm designed to find eigenvalues and eigenvectors of a given matrix faster than classical algorithms. It is an important subfield of quantum ...

Abstract: This paper proposes a signal sensing method based on principal components to minimum eigenvalue of the received signal. The signal model and theoretical performance analysis of the principal ...

In this paper, the Eigenvalue Complementarity Problem (EiCP) with real symmetric matrices is addressed, which appears in the study of contact problem in mechanics. We discuss a quadratic programming ...

We introduce a novel eigenvalue algorithm for near-diagonal matrices inspired by Rayleigh-Schrödinger perturbation theory and termed Iterative Perturbative Theory (IPT). Contrary to standard ...
