Programming Quantum Computers - by Eric R Johnston & Nic Harrigan & Mercedes Gimeno-Segovia (Paperback)

About the Book

Book Synopsis

Quantum computers are poised to kick-start a new computing revolution--and you can join in right away. If you're in software engineering, computer graphics, data science, or just an intrigued computerphile, this book provides a hands-on programmer's guide to understanding quantum computing. Rather than labor through math and theory, you'll work directly with examples that demonstrate this technology's unique capabilities.

Quantum computing specialists Eric Johnston, Nic Harrigan, and Mercedes Gimeno-Segovia show you how to build the skills, tools, and intuition required to write quantum programs at the center of applications. You'll understand what quantum computers can do and learn how to identify the types of problems they can solve.

This book includes three multichapter sections:

• Programming for a QPU--Explore core concepts for programming quantum processing units, including how to describe and manipulate qubits and how to perform quantum teleportation.
• QPU Primitives--Learn algorithmic primitives and techniques, including amplitude amplification, the Quantum Fourier Transform, and phase estimation.
• QPU Applications--Investigate how QPU primitives are used to build existing applications, including quantum search techniques and Shor's factoring algorithm.

About the Author

Eric Johnston (EJ) is the creator of the QCEngine quantum computation simulator, and also an acrobat and competitive gymnast. As an engineer, EJ values surprise and whimsy above all other things. He studied Electrical Engineering and Computer Science at U. C. Berkeley, and worked as a researcher in Quantum Engineering at the University of Bristol Centre for Quantum Photonics. EJ worked at Lucasfilm for two decades as a software engineer for video games and movie effects, along with occasional motion-capture stunt performance.

Alongside developing strategies for encoding information within quantum computers, Nic has also worked extensively in the foundations of quantum mechanics. His time grappling with the fundamental meaning of quantum physics has uniquely equipped him to convey (and sometimes judiciously avoid) it's finer details. He also has 10+ years experience working in science communication, having developed numerous public lectures, workshops and educational resources aimed at conveying complex physics topics to a general audience. Along with work in other media (eg: television, radio), his public engagement work has won various awards (eg: NESTA UK Famelab winner) and been recognized by a visit to 10 downing street. He also has a lifelong passion for more conventional computing and machine learning.

Mercedes Gimeno-Segovia is a world-class researcher in quantum computing. She has a PhD in Quantum Computing Architectures from Imperial College London, and 7+ years of research experience in the field. Her PhD thesis has become a milestone in the field of linear optical quantum computing, as her design of a linear optical architecture overcame many challenges thought unsurmountable and proved to be feasible using current manufacturing techniques. Mercedes has expert knowledge on the limitations of quantum computing implementations, and is passionate about understanding every last detail of a physical system in her quest to find optimal quantum computing hardware. She enjoys science communication, writing a blog and giving public lectures to young students. She's also an accomplished violinist, having finished qualifications in violin performance and winning an extraordinary award during her studies.
