Quantum mechanics lectures, courses and text
Courses
David Miller teaches a sequence of two quantum mechanics courses appropriate for any level from Junior (third year) or Senior (fourth year) undergraduates in science and engineering, through to graduate students and technical professionals. He has taught these courses to many thousands of Stanford graduate and undergraduate students from a broad range of science and engineering backgrounds for many years.
Open online classes
He has also taught two corresponding online versions of these classes to over 50,000 students. These open online classes are currently available as student-paced classes through edX and Stanford Online. Online lectures, slide copies, FAQs, and some other material are available in a progressive and coordinated sequence at no charge in these online classes. Other material, including extensive online quizzes and assignments (all with solutions), and earned certifications are available for a fee. See the following links
Video lectures
The videos, lecture slide copies, and FAQs are also available directly here.
The lecture videos themselves are also available through this YouTube channel
as well as through a YouTube playlist.
Textbook

David Miller’s text supports all these lectures and classes. (This book is not required for the online classes, which are self-contained, but it contains deeper discussions of many topics as well as significant additional material, and the courses follow the textbook closely.)
