Renato Portugal graduated in Physics from the Pontifical Catholic University of Rio de janeiro in 1981 and obtained his PhD degree in Physics at the Brazilian Center for Research in Physics in 1988. He was a visiting professor at the University of Waterloo in 1997 and 2008 and at the Queen's University at Kingston in 1998 in Canada. He is currently a full researcher at the National Laboratory of Scientific Computing (LNCC). Currently, he is working in the area of quantum computing with focus on the following subareas: algorithms for quantum computing, analysis and simulation of quantum walks, and classical cryptography.Franklin de Lima Marquezino graduated in Computer Science from the Catholic University of Petropolis in 2004, and received his PhD degree in Computer Modelling form the National Laboratory of Scientific Computing (LNCC) in 2010. He stayed for one year as postdoctoral researcher also at LNCC. Since 2011, he is an associate professor at the Federal University of Rio de Janeiro, working mainly in the areas of quantum algorithms and quantum walks.Carlile Lavor graduated in Mathematics from the University of Campinas in 1996, and received a PhD in Computer Science from the Federal University of Rio de Janeiro, in 2001. He was a visiting professor at prestigious institutions like École Polytechnique (2008-2009) and Duke University (2013-2014). Since 2005, he has been working at the University of Campinas, where he is now a full professor. He is co-author of the books "Euclidean Distance Geometry" and "A Geometric Algebra Invitation to Space-Time Physics, Robotics and Molecular Geometry" and co-editor of "Distance Geometry: Theory, Methods and Applications" book, all by Springer.

“The authors provide enough material for students of computer science and mathematics to learn the basic rules of quantum mechanics. The authors also provide enough information for students of physics and engineering to understand the basic concepts of algorithm design and its analysis. There are many interesting quantum algorithms worth learning. … This book is written in a way that is easy to read. It is suitable for beginners who are interested in learning quantum algorithms.” (D. J. Guan, Mathematical Reviews, May, 2020)“This simple yet practical first contact with quantum computing is well written, easy to read, and well structured. … the book is exceptionally interesting for people in CS who want to understand the basic notions behind quantum computing.” (Santiago Escobar, Computing Reviews, October 09, 2019)
