This repository aims to contain definitions and proofs of basic ideas in quantum information theory. Some major goals, in rough order of difficulty, would be ...

Abstract: Multigrid (MG) methods are among the best choice for stable and efficient 3D forward modeling of electromagnetic (EM) fields over large area due to their linear dependence of computational ...

Abstract: We propose a new form of the bounded real lemma (BRL), dedicated to finite impulse response (FIR) multiple-input-multiple-output systems. The proposed form is more efficient than the usual ...
