The quest to build a quantum computer is arguably one of the major scientific and
technological challenges of the twenty-first century, and quantum information theory (QIT) …

This book is intended to accompany a second course in linear algebra, either at the
advanced undergraduate or graduate level. The only prerequisites that are expected of the …

The structure of the set of positivity-preserving maps between matrix algebras is notoriously
difficult to describe. The notable exceptions are the results by Størmer and Woronowicz from …

A new method of analysing positive bistochastic maps on the algebra of complex matrices M
3 has been proposed. By identifying the set of such maps with a convex set of linear …

Partindo da abordagem matemática de geometrias clássicas, uma abordagem linear para
modelos geométricos que aparecem com frequência em Física (eg Fubini-Study …

This thesis mainly concerns the interplay between positive linear maps and quantum
entanglement. In the first part of the thesis, after the preliminary Chapter 1 setting up …
