FAQ

Is this book suitable for undergraduate students?

It's primarily a graduate text and quite rigorous. Advanced undergrads might use it, but expect a challenge. A solid background in undergrad QM and mathematical methods is reccomended.

What mathematical background is needed?

You'll need a strong foundation in linear algebra, differential equations, and complex analysis. The book is mathematically intensive, so be prepared!

How does this compare to Griffiths' 'Introduction to Quantum Mechanics'?

Griffiths is typically used for undergraduate courses and focuses more on intuition and problem-solving for standard potentials. Sakurai/Napolitano is more mathematically formal, abstract, and comprehensive, suitable for the graduate level.

What's new in the 3rd Edition compared to the 2nd?

Jim Napolitano updated the text, reorganized some material, added new topics and problems (like quantum computation introductions), and refined explanations based on decades of teaching experience, ensuring its relevance for modern physics students.

Are solutions to the exercises available?

Solutions manuals often exist for instructors, but finding a complete, publicly available student solutions manual can be difficult. Focus on working through the problems yourself or with study groups is the best way to learn!

Is this book good for self-study?

It can be used for self-study if you have a very strong math and physics background and are highly motivated. However, its rigor and depth make it quite challenging without the structure of a course or guidance.

Reader Reviews

★★★★★
PhysicsGradStudent91(Graduate Student)
The absolute bible for grad QM. Incredibly challenging but builds such a deep understanding. Couldn't survive my qualifying exams without it.
★★★★☆
AspiringPhysicist_23(Advanced Undergrad)
Very dense and mathematically heavy, definitely not for the faint of heart or as a first intro. But the depth is incredible once you start getting it. Takes time to digest.
★★★★★
Dr_Theory(Physics Professor)
This is the standard text I reccomend for my graduate quantum mechanics course. Sakurai's logical structure is classic, and Napolitano's updates keep it fresh and modern. Excellent book.
★★★☆☆
QM_SelfLearner(Independent Researcher)
Tried using this for self-study after finishing Griffiths. It's tough going without guidance. Very rigorous, maybe too much for independent learning unless you're *really* dedicated and have strong math skills.
★★★★★
ParticlePhysicist_Gal(Postdoc Researcher)
An indispensable reference book. I still consult my copy regularly for formalism and advanced topics. Covers almost everything you need with clarity and rigor. The chapter on symmetries is gold.
★★★★☆
TopUndergrad_Physics(Physics Undergraduate)
Used some chapters for an advanced undergrad project. Way more formal than introductory texts, but it really forces you to understand the underlying structure of QM. Hard work, but worth the effort.
★★★★☆
QuantumQuant(Physics Enthusiast)
A masterpiece of physics literature. Its not an easy read, make no mistake, but the clarity on fundamental principles is unmatched. The updates in the 3rd edition are welcome.

About the Author

J. J. Sakurai (1933–1982) was a highly influential Japanese-American theoretical physicist celebrated for his profound contributions to quantum mechanics and particle physics. His insightful lecture notes formed the basis for this classic text. Jim Napolitano, a respected experimental nuclear physicist and dedicated educator, skillfully revised and updated the book for this 3rd edition, preserving Sakurai's invaluable legacy while incorporating modern advancements and perspectives for today's students.
