SUMMARY:Realism and the epistemic view of quantum states\, Physics Dep
 artment Colloquium\, Terry Rudolph
DESCRIPTION:The idea that quantum states reflect only an observers kno
 wledge/beliefs/information about the world has a long history. The cha
 llenge for an advocate of this position\, however\, is to identify wha
 t we can deduce is "really going on'' out there. There seem to three m
 ain paths proponents of the epistemic view have followed in trying to 
 extract such a narrative from quantum theory. I will explain how the m
 ost naïve such path--that quantum states can be associated with stand
 ard (probabilistic) uncertainty about some (arbitrary) real states of 
 the world--is not tenable under some extremely mild assumptions about 
 how any theory of reality must treat independent experiments. I will t
 hen overview the other two paths and what I see as the challenges they
  face.
