Quantum Information Science

This book provides an introduction to quantum information science, the science at the basis of the new quantum revolution of this century. It teaches the reader to build and program a quantum computer and leverage its potential. Aimed at quantum physicists and computer scientists, the book covers several topics, including quantum algorithms, quantum chemistry, and quantum engineering of superconducting qubits. Written by two professionals in the experimental and theoretical fields of quantum information science and containing over 200 figures and 100 exercises with solutions and summaries at the end of each chapter, this book is set to become a new standard in the field.

Riccardo Manenti earned his DPhil at the University of Oxford in 2017 with a thesis investigating the coupling between a superconducting qubit and a mechanical oscillator based on surface acoustic waves. His research contributed to the formation of a new research field, now called circuit quantum acousto-dynamics. He is currently a Senior Quantum Engineer at Rigetti Computing, a quantum computing company based in Berkeley, California. Mario Motta earned his Ph.D. at the University of Milano in 2015 with a thesis on quantum Monte Carlo simulation of fermionic systems. After postdoctoral positions at the College of William and Mary and the California Institute of Technology, he became a Research Staff Member at IBM Almaden Research Center in 2019.
