SUMMARY:Free randomness can be amplified - Renato Renner (ETH Zurich)

DESCRIPTION:A standard (and usually implicit) assumption in physics is tha
 t experimental parameters can be chosen "freely". For example\, the conclu
 sions we draw from Bell-type experiments are generally only valid if the m
 easurements are selected at random.  In this talk\, I consider a situation
  where this assumption is weakened and ask whether the standard conclusion
 s we draw in physics are still valid. As a possible path towards an answer
 \, I will show that it is possible to turn "partially free randomness" int
 o "fully free randomness" --- a task that is provably impossible in a pure
 ly classical world.
