Switch to Physics from CS Career I've been considering a career change for awhile 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, 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. 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.
I'm considering Astrophysics as a minor (due to interest), but wondering whether it would be useful and complementary to Quantum Theory.


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.
Yes you can leverage.  At my university, these people work in the EECS department.  You could just apply to be a graduate student.
Study vector calculus and linear algebra.
Not really.  However, "big data" is quite popular in astro/astrophysics currently, so maybe you could get hired as a programmer.
