The New Quantum Era: An Outsider's Introduction

Explore quantum computing concepts and separate hype from reality with a clear, accessible guide to this emerging technology

Key Features

• Explore quantum computing concepts without complex math or code
• Understand the history, challenges, and future of quantum technologies
• Distinguish real progress from hype in quantum technologies

Book Description

Make sense of quantum computing without needing a background in physics or mathematics, and cut through growing industry hype to understand what’s real and what’s not. This book provides the clarity needed to understand what quantum computing is, what it can realistically achieve, and where it stands today.

Drawing on decades of experience in emerging technologies, Sebastian Hassinger presents a clear, narrative-driven exploration of quantum computing. The book explains the key ideas, historical breakthroughs, and technological challenges that define the field without focusing on equations or programming. You will explore how quantum mechanics reshaped information theory, why classical computing faces limits, how quantum approaches attempt to overcome them, and the experimental origins of quantum technologies.

Through real-world context and industry insights, the book examines current hardware, competing approaches to building qubits, and the realities of today’s rudimentary systems. It also addresses common misconceptions and inflated expectations, helping you critically evaluate claims made by companies and researchers.

By the end of this book, you will have a grounded understanding of quantum computing’s capabilities, limitations, and future direction, enabling you to engage confidently with this rapidly evolving field.
