Info request on studying QIT/QIS or QM with a Computer Science background I've been considering a career change for a long time and recently discovered the Two-Slit Experiment, which, to put it frankly, blew my mind.  I then started some hefty reading and investigation into all things Quantum (Bell, Campbell, entanglement, QIT), which has led me here.
I have 20 years experience in IT working as a programmer, having graduated with a Bachelor in Computer Science back in the early 90s.  As mentioned, I have been considering a career change for some time (having become quite burned out in this industry), and have found something that has piqued my interest more than anything else (tho I did consider Astrophysics a couple of years ago).  I am not yet sure which area of "Quantum" I will be most drawn to, possibly Quantum Information Theory/Science. 
I am aware that there is a significant amount of Maths and Physics pre-requisites involved.  It seems likely, given that I have not done any Maths or Physics study probably since I was doing my CS undergrad, that I will need to start over with an undergrad in Science/Physics in order to get the fundamentals.
So my questions are:


*

*What is the ideal path of education to get to QIT/QIS or QM?

*Is the path to QIT/QIS also via the Physics route?  Can I leverage my CS background?

*Resources (books, online courses, etc) that would help with the transition from CS-type thinking to Physics/Maths-type thinking.
Apologies if this encompasses elements too broad or off-topic, I'm trying to get a better understanding on what is to come following this path.  Thanks in advance.
 A: I'm only a grad student myself, but this is my take on the subject:

Any advice on the best path of education to get to QIT/QIS or QM?

Difficult, as depending on what you want to learn. Generally speaking, there are many different routes - you can go via maths or via physics. You probably whant to start out with quantum computation, since this is nearest to your field. You'll find enough material there to work on (especially quantum complexity theory). 

Is the path to QIT/QIS also via the Physics route? Can I leverage my CS background?

Naturally, the usual path would be to learn quantum mechanics and build from there. You can learn quantum mechanics either with an applied background, focused on doing calculations and understanding the phenomenology of experiments, or you can go and study the mathematical framework directly and study physics from there. Neither of these two "natural" approaches lets you use your CS background very much, but if you go directly into quantum computations, you might find it easy to go from there.

Any suggestions on resources (books, online courses, etc) that would help with the transition from CS-type thinking to Physics/Maths-type thinking.

There are many resources - as already mentioned in the comments, Nielsen&Chuang is a very good starting point. There are not many requirements needed to read this book and it has a mixture of CS and QM. If you know everything that's in there, you have a good background to go into every other field. Generally speaking, if you want to start out with finite dimensional quantum mechanics/information, all you'll need is linear algebra (and that's what Nielsen&Chuang needs) and I hope, as a computer scientists, you know that.
If you want math heavy books on quantum mechanics, there are many, e.g. a wonderful book by Holevo "Probabilistic and Statistical Aspects of Quantum Theory". 
As a teaser, maybe you want to have a look at the book "Quantum Computing since Democritus" (something in between a popular science book and a real course book) by Scott Aaronson (also, have a look at his web resources). He's a complexity theorist who got into the field as a computer scientist and (from my perspective) still thinks this way. If you like complexity theory, this might be an interesting starting point for you!
