| Mar 13, 2014 at 19:17 | comment | added | garyp | I'm going to renege slightly on my offer. It takes a quite a bit of notation, which I can't offer right now. But the idea is not that complicated. I will offer a link. It was surprisingly difficult to find a simple presentation that would answer your question. this link is a start, but it doesn't show how calculation of, e.g., expectation values works out. If I find a good link, I'll post it. | |
| Mar 13, 2014 at 17:25 | comment | added | AlanHarper | Thank you for your answer. That is exactly what I am concerned about - what about all those observables! Once I realized that different observables may have different number of eigenstates (thus these eigenstates have to span different state spaces), my confusion about measurement and expansion of the state in basis eigenstates of the corresponding observable started. Could you provide more information about the direct product space, please? | |
