From the reviews:

„Daniel Bes clearly understands that accuracy, clarity and brevity … . has therefore made a careful selection of the topics to make an accessible concise book on quantum mechanics for a modern introductory undergraduate course. The book has several good features. The claims that this is a modern textbook are well justified by the inclusion of … . the flow of the main ideas is not unbalanced by laborious detail.“ (Professor J. E. Carroll, Contemporary Physics, Vol. 46 (4), 2005)

„This book accomplishes all the goals implied by its title: it is ‘modern’, ‘concise’ and ‘introductory’. It is concise (just two hundred pages) but covers an extraordinary range of topics, from those typically found in traditional quantum mechanics textbooks … . All this is illustrated with examples that cover a wide range … . This book provides a large amount of information per page and the selection, extension and balance of topics is adequate for an introductory course.“ (Adán Cabello, Mathematical Reviews, 2005)

„The author has nicely made a systematic dual presentation of both the Heisenberg matrix mechanics and Schödinger wave mechanics … . This wonderful textbook will certainly be a valuable addition to the physics/chemistry library of a science college/university/institute.“ (Samir Saha, Indian Journal of Physics, Vol. 79 (12), 2005)

„This book is a very clear, comprehensive, concise, and updated introduction to quantum mechanics (QM). … Bes’ book has a great advantage over the other texts: it is updated with some of the most recent advances in quantum theory, including quantum computation and teleportation. The book is supposed to be suitable to undergraduate and first year graduate students. … The problems in the book are few but very stimulating. Besides, there are many figures, graphics, and tables, that really help the reader.“ (Adonai S. Sant’Anna, Zentralblatt MATH, Vol. 1052, 2005)
