Apologies if this is in the wrong place.
It's true that most of the mainstream physicists (rightly - for practical purposes) don't care about these matters, but there is a whole community working on this, however, it's not called "Quantum Philosophy", as most people don't want to do philosphy, rather it is "Foundations of Physics" - or mostly "Foundations of Quantum Theory" or just "Quantum Foundations". Especially within the border of quantum information theory, there are a lot of people quite interested in hidden variable models, theories beyond quantum theory and generally exploring the foundations of physics. Axiomatization (e.g. via "Quantum Logics") always has a philosophical component, hence it is maybe "quantum philosophy". Papers dealing with hidden variable, loopholes in Bell experiments, alternative theories, etc. will mostly be put under the quant-ph ArXiv-Tag.
Important groups I know of working on this from different angles are groups on Bohmian mechanics (Munich or I think it was Rutger's), Quantum information people (e.g. groups at Perimeter institute and Vienna) or with completely different agendas (e.g. Gerhard t'Hooft).
But beware: The subject of quantum foundations is a matter of taste. There are a lot of fringe ideas and rather crazy people around there, so (as always in philosophy, I guess) it's hard to make out the good bits, without deeply delving into the subject.
Personally, I believe that trying to understand the foundations of quantum mechanics (e.g. solving the measurement problem, etc.) is an important endeavour, but it might have no impact on applications whatsoever, which is, why it's something to do in your freetime with the help of philosophers.
Very few physicists in my school's department seem to care about these questions. The "history and philosophy of physics" tag on arXiv lists only a single page of papers. I believe John Bell worked on these questions as an avocation. That said, there are a lot of different ways to approach "philosophy of physics" type questions, and you can pose such questions more towards the physics side of things. But, judging by appearances, it would seem philosophy departments are more interested in these questions than physicists are.
