Hi I have a question about POVMs(adsbygoogle = window.adsbygoogle || []).push({});

im confused as to how they correspond to actual measurements we do in a lab, and how non-orthogonal measurements fit into this context. For example we have some POVM with elements [itex]E_i[/itex]. I read in Nielsen and Chuang that we do a measurement and get outcome m say. Now what does this correspond to? if the POVMs were projectors then for the different elements [itex]E_i[/itex] we would have different experimental setups is this the same for POVMs or is it one setup with multiple outcomes?

And I guess for non-orthogonal measurements Im just confused as to whether they can be represented by POVMs

thanks

Mark
