I have just moved to the Center for Quantum Technologies in Singapore, after spending the last 3 years as a Merton College JRF in Theoretical Physics and a Senior Research Fellow in Oxford University Department of Materials. My research focuses largely on theoretical aspects of quantum information processing. In particular I am interested in spin networks, measurement based computation, cryptography and computational complexity.

So, why are people voting to close without leaving a comment?

Actually, the courses you end up teaching are often not entirely dependent on your expertise. More often it is a case of what courses need teaching when you join the department.

comment Why can't the outcome of a QM measurement be calculated a-priori?
There have been a lot of papers written on this, but they are philosophy not physics. The practical answer is that there are multiple possibilities, and by the pigeon hole principle you must get one of them. For the probabilities, etc., see Everett's thesis or more recent review papers.

@Sklivvz Well, this all depends on interpretations, but sticking with the Everett interpretation it is that we perceive both in different branches of the wave function but each branch is unaware of the other.

comment The Many Body problem
Yes, that is true. Calculating ground states seems to be beyond their reach though.

comment The Many Body problem
It definitely can only make things harder as you can encode a discrete system in the CV but not necessarily the other way around.

By which I mean the problem with simulating the system, not a problem with your answer.

comment The Many Body problem
The problem here, of course, is that the field modes are continuous variables.
