I'm a Professor of Physics at Reed College. Before coming to Reed I taught at Whitman College in Walla Walla, WA for manyyears. I got my B.S. in Optics from the Univ. of Rochester in 1985, and myPh.D. in Optics from the U of R in 1992. I did a post-doc at the University ofOregon after completing my Ph.D.
My main fields of study are quantum optics and laser physics. I'm anexperimentalist interested in producing light fields which cannot be describedusing classical mechanics, especially if the experiments can be carried out byundergraduates. I'm also interested in fundamental questions about quantummechanics (measurement theory, etc.), as well as physics education.
I've developed a series of undergraduate teaching labs that explore somefundamental principles of quantum mechanics. These experiments include proving theexistence of photons, single photon interference and entanglement of two photons.I've also written a quantum mechanics textbook: QuantumMechanics, Theory and Experiment, which is intended for use in a junior/seniorlevel undergraduate course.

The Spin First Approach to Quantum Mechanics is a theoretical framework for understanding the behavior of subatomic particles, such as electrons and protons. It places a strong emphasis on the intrinsic angular momentum of particles, known as spin, as opposed to traditional approaches that focus on position and momentum.
The Spin First Approach differs from other approaches in that it considers the spin of particles as a fundamental property, rather than an emergent phenomenon. This allows for a more intuitive and mathematically elegant understanding of quantum mechanics, and has led to new insights and predictions in the field.
The key concepts in the Spin First Approach include the spin of particles, the concept of quantum entanglement, the role of symmetries in quantum systems, and the use of Clifford algebras in describing the behavior of particles.
The Spin First Approach explains quantum phenomena by considering the spin of particles as the primary factor in determining their behavior. This approach has led to a better understanding of concepts such as superposition, entanglement, and the measurement problem in quantum mechanics.
The Spin First Approach has been applied to a variety of fields, including quantum computing, condensed matter physics, and quantum information theory. It has also led to new insights into the behavior of particles in high-energy experiments, and has the potential to revolutionize our understanding of the fundamental laws of nature.

I'm really interested in quantum theory and would like to learn all that I can about it. I've followed a few tutorials and read a few books but none satisfied me completely. I'm looking for introductions for beginners which do not depend heavily on linear algebra or calculus, or which provide a soft introduction for the requisite mathematics as they go along.
Introduction to Quantum Mechanics by David Griffiths, any day! Just pick up this book once and try reading it. Since you have no prior background, this is the book to start with. It is aimed at students who have a solid background in basic calculus, but assumes very little background material besides it: A lot of linear algebra is introduced in an essentially self-contained way.
Furthermore, it contains all the essential basic material and examples such as the harmonic oscillator, hydrogen atom, etc. The second half of the book is dedicated to perturbation theory. For freshmen or second-year students this a pretty good place to start learning about QM, although some of the other answers to this question suggest books that go a bit further, or proceed at a more rigorous level.
is heavy on good exercizes and mathematical tools. L&L include topics not covered everywhere else. The standard undergraduate books on quantum mechanics are not very good in comparison to these, and should not be used.
You can also read the Wikipedia page on old quantum theory for a sketchy summary, then look at the page on matrix mechanics. This explains the intuition Heisenberg had about matrix elements, something which is not in Dirac's book or anywhere else. Heisenberg's reasoning is also found to certain extent in the first chapters of this book:
Next, watch the "Theorectical Minimum" videos by Leonard Susskind . They represent the theoretical minimum that you need to know about quantum mechanics. (i.e. the title of the video course is theoretical minimum, but it is in fact a course on quantum mechanics. Susskind is a great teacher and the videos are great. You can access them on itunes and You Tube. Search for Susskind lectures quantum mechanic from Stanford. They are just released (a few weeks ago)
Finally, the text you want is Principles of Quantum Mechanics by Shankar. He is also a great teacher. He does have some video lectures on general physics, but he does not have a video lecture on Quantum Mechanics. Nonetheless, his book is a great book for learning. It is about $70, but if you google around (with PDF in your google search) you may get lucky.
If you are not willing to learn the linear algebra upon which the entire theory of quantum mechanics is based, then you really aren't going to have much luck finding the kind of textbook you seek. It sounds to me like what you want is a textbook that introduces you to what is called "modern physics" instead. Most "modern physics" texts cover quantum mechanics concepts while remaining mostly in algebra land. Most of the textbooks recommended in the answers posted before mine are chock full of calculus.
Learning how to multiply matrices and vectors isn't hard at all -- you can learn it from a Wiki, from YouTube, or Khan Academy. Once you know how to do that, I strongly recommend the first few chapters of the following textbook:
I used this book the last time I taught quantum mechanics, and the students really liked it a lot. You can teach yourself "real" quantum mechanics from this book using the Dirac bra-ket notation used in real physics research and in quantum information theory.
I used to use Griffiths' text due to its popularity and the due to the traditional stress on the wave function. However, my students did not get as much out of the Griffiths' text as they do from the two I mentioned above. Furthermore, I am now convinced that students are better served by learning the state-vector approach instead of focusing solely on the wave function, as it allows them to read recent papers about breakthroughs in QM research. You can't do too much with wave functions when your experiment deals with particle spins or with photon polarizations.
Don't know why this has dropped out of fashion-- people complain it is too much oriented towards nuclear physics. Well I am a physical biochemist turned magnetic resonance jock, and I find it excellently adapted to my needs.
The problem here is that there are no easy good books. The subject is intrinsically hard. Earlier responders cited Landau and Dirac; Landau is another favorite of mine, but harder than granite-- Dirac is brilliant but legendary for difficulty. Reading Dirac is like trying to climb a sheer marble wall-- footholds and handholds are not abundant. Landau (at least) often gives a good physical reason why such and such thing should be so, before he starts writing equations. Be prepared to spend much time meditating on his meaning.
A book for self study to get you from introductory QM to elementary is Claude Cohen-Tannoudji's Quantum mechanics textbook which is in two volumes. It has a very high price but it deserves it. It has all the glory details inside! (Shankar's book is also great and is on the same level and also covers path integrals. Griffiths' is only introductory, although it also has some chapters that other books on the same level do not have)
These books will be with you from this level to a PhD level. Very useful books. And except for only using them to master the things that the above books have taught you, you will find them to be very useful for mastering stuff from more advanced textbooks (graduate and advanced undergraduate).
Quantum Physics by V.Balakrishnan. The instructor introduces all the basics of linear algebra you need, But you will have to work very hard On your own because he will also introduce a lot of other fancy math that you might need(for instance he will speak about L^2- spaces.)I do not know a proper book that goes along with the course (Other's might recommend that)
Quantum Physics By JJ Binney. This is also a very nice introductory course taught to undergraduate students at Oxford. This might be something that will help you a lot. The book that goes along with the course is also available by the same author (free of cost) here.
The QM course by Alan Adams in MIT is very very awesom.IMHO,he is the best teacher .Best part in it is that he inspires the students to ask questions and the MIT students ask so many good questions,that also helps the person who is watching the video lectures.In the site you will also find books that goes along with the course. -04-quantum-physics-i-spring-2013/
Here you will find the same story as physicists tell there own students. The difference is that this book is designed to be much easier to read and understand than comparable texts. Quantum mechanics is inherently mathematical, and this book explains it fully. But the mathematics is only covered to the extent that it provides insight in quantum mechanics. This is not a book for developing your skills in clever mathematical manipulations that have absolutely nothing to do with physical understanding. You can find many other texts like that already, if that is your goal.
