Quantum Computing: From Linear Algebra To Physical Realizations by Mikio Nakahara – A Comprehensive Textbook on Quantum

Introduction

Quantum computing represents the next frontier in computational science, promising to solve problems that are intractable for classical computers. Quantum Computing: From Linear Algebra To Physical Realizations by Mikio Nakahara offers a rigorous yet accessible journey from the mathematical foundations to the experimental implementations of quantum computers. Published by CRC Press, this hardcover volume is an indispensable resource for Indian students, researchers, and professionals seeking a deep understanding of this transformative field.

Book Overview

This book bridges the gap between abstract theory and practical hardware. It begins with the essential linear algebra and quantum mechanics, then progresses through quantum gates, algorithms, and error correction. The second half explores real-world physical realizations—from trapped ions to superconducting qubits—evaluating them against the DiVincenzo criteria. The text is classroom-tested and self-contained, making it suitable for both self-study and university courses across Indian institutions.

Key Highlights

• Comprehensive coverage from fundamental mathematics to cutting-edge experimental systems.
• Classroom-tested pedagogy with clear explanations and worked examples.
• Focus on physical realizations including NMR, ion traps, optical systems, and solid-state qubits.
• DiVincenzo criteria used as a framework to evaluate quantum computing platforms.
• Includes quantum error-correcting codes essential for building fault-tolerant systems.

Inside the Book

The book is divided into two logical parts. Part I covers the theoretical backbone: linear algebra review, principles of quantum mechanics, qubits, quantum key distribution, quantum gates, simple quantum algorithms, quantum Fourier transforms, Grover's search algorithm, Shor's factorization algorithm, decoherence, and quantum error correction. Part II dives into experimental implementations, discussing NMR quantum computing, ion trap quantum computers, optical approaches, and solid-state qubit systems. Each chapter builds on the previous, ensuring a smooth learning curve.
