Quantum Information. The Basics.

Scores of physicists- the world over-will tell you that one of the finest books from which one might learn quantum mechanics is Principles of Quantum Mechanics by R Shankar, published by Plenum Press.

The good news for us all is that finally this book has become available in an Indian edition, courtesy Prism, a small publisher based in Bangalore, but one who has been interested in making quality texts available in the country, along with Springer, India.

Shankar, Professor of Physics at Yale University, is very well known both for his research as well as for his approach to pedagogy. And he has a charming self-deprecatory style- his webpage lists his most important contribution to physics as his discovery of a "small parameter that justifies most calculations performed in physics: 1/ego, where ego is the author's ego".

In this edition, Shankar has introduced major additions and updated key presentations. New features of this innovative text include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications. Additional highlights include a clear, accessible treatment of underlying mathematics and a review of Newtonian, Lagrangian, and Hamiltonian mechanics. The student's understanding of quantum theory is enhanced by separate treatment of mathematical theorems and physical postulates. The book is particularly well known for its coverage of path integrals and their relevance in contemporary physics.

A widely admired text for advanced undergraduate- and graduate-level students, Principles of Quantum Mechanics is fully referenced and is supported by many exercises and solutions. The book’s self-contained chapters also make it suitable for independent study as well as for courses in applied disciplines.
Shankar's other well-known book is Basic Training in Mathematics: A fitness program for science students, also from Plenum (but unfortunately not yet also from Prism).
