To simplify a complex topic, quantum mechanics can be defined as the branch of physics that attempts to explain how the universe works at the atomic and subatomic levels.
This means that quantum mechanics is vastly different from classical physics—it follows different principles. While they may be mathematically straightforward, conceptualizing things that do not behave according to a macroscopic understanding of reality can seem insurmountable to newcomers.
The following five books are considered some of the best introductory quantum mechanics textbooks. They offer a helping hand to newcomers through different strategies and perspectives. They cover introductory subjects such as fundamental conceptualizations, thorough explanations of principles, applications, and more.
Whether you are a student or a layman with intellectual pursuits, these books are excellent tools to help you understand the most challenging branch of physics.

Best Introductory Quantum Mechanics Textbooks
Introduction to Quantum Mechanics
by David J. Griffiths and Darrell F. Schroeter
Introduction to Quantum Mechanics by Griffiths and Schroeter is a well-regarded textbook for quantum mechanics and one of the most commonly used undergraduate texts on the subject.
Praised for its straightforward writing style and excellent command of the fundamentals, it is as comprehensive as a beginner’s text should be. The problems are challenging yet engaging, as solving them will introduce readers to some of the most essential quantum mechanics concepts through practical effort.
Quantum Mechanics: Concepts and Applications
Zettili’s Quantum Mechanics has long been a favorite for students and self-taught enthusiasts everywhere due to its beginner-friendly approach and overly detailed explanations that cover even ground in the field.
The book starts with the experimental basis of quantum mechanics, highlighting how classical physics fails to explain atomic and subatomic phenomena before delving into the discipline’s mathematical tools, formal foundations, the Schrodinger equation, and more.
The book is praised for combining essential theoretical concepts with practical applications through easy-to-understand examples, numerous problems, and their respective step-by-step solutions.
Quantum Mechanics, Volume 1: Basic Concepts, Tools, and Applications
by Claude Cohen-Tannoudji, Bernard Diu, and Franck Laloë
Eventual Nobel laureate Claude Cohen-Tannoudji wrote Quantum Mechanics Volume 1 alongside his colleagues Bernard Diu and Franck Laloë in 1973, unaware that it would become one of the cornerstones of undergraduate-level quantum mechanics textbooks.
Divided into seven chapters, they cover the wave-particle duality as the introductory basis of quantum mechanics, then explain mathematical tools, the postulates of quantum mechanics, and more. Each chapter ends with a reader’s guide to further understanding.
Principles of Quantum Mechanics
Principles of Quantum Mechanics is a long-time favorite for the basics of the subject, particularly because of its informal, conversational written style.
However, its most outstanding contribution to the conversation is its mathematical rigor. Unlike other textbooks, Shankar opens with linear vector spaces, bra-ket notations, and other mathematical aspects instead of starting with the postulates of quantum mechanics.
However, remember that as comprehensive as this book is, some readers claim it’s among the most complex introductory quantum mechanics textbooks and describe it as quite theory-heavy. Therefore, using it as a graduate-level read or supplementary material alongside other texts might be the best approach.
The Feynman Lectures on Physics. Vol. III: Quantum Mechanics
by Richard Feynman, Robert B. Leighton, and Matthew Sands
The Feynman Lectures are considered some of the greatest in the history of physics, but they were not conceived as textbooks from the start. As their name implies, they’re based on lectures given by Nobel laureate Richard Feynman to the California Institute of Technology undergraduate students from 1961 to 1964.
Quantum Physics is covered in Vol. III, and is perhaps the most well-known of the entries in the series, not in small part because Feynman’s Nobel Prize was for his study of quantum electrodynamics.
The textbook starts by describing quantum behavior, moves on to the relation between wave and particle viewpoints, and explores the rest of the basics of quantum mechanics in an approachable yet in-depth manner.
The Perfect Introductory Quantum Mechanics Textbook Depends on You
Learning quantum mechanics is far from intuitive. Small things on the atomic and subatomic levels behave unlike anything you’ve ever had direct contact with. As such, learning quantum mechanics involves a lot of unlearning, making it a complex process.
Choosing the right book for beginners can give you the tools to navigate this process, but not all books are the same. Each has a different approach, writing, and teaching method worth exploring—the right one will click with your learning style and make the journey a breeze.
