(Un-)decidable problems in quantum theory (Prof. M. Wolf)

  • Date: Oct 20, 2015
  • Time: 14:30 - 16:00
  • Speaker: Prof. Dr. Michael Wolf, Zentrum Mathematik, M5, Technische Universität München
  • Room: Herbert Walther Lecture Hall
  • Host: MPQ
In the talk I will review recent results on the (un-)decidability of problems in quantum many-body physics and quantum information theory.

In both fields there is a natural integer limit that opens the door to undecidability of some of the central properties: the thermodynamic limit in quantum many-body theory and the large block-size limit in information theory. I will try to illuminate the thin line between computable and uncomputable and to illustrate possible physical consequences of unprovable properties.
