DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/IFQ/2
 /">The Python's Lunch: geometric obstructions to decoding Hawking radiatio
 n</a>\nby Hrant Gharibyan (Caltech) as part of It from Qubit\n\n\nAbstract
 \nHarlow and Hayden [arXiv:1301.4504] argued that distilling information o
 ut of Hawking radiation is computationally hard despite the fact that the 
 quantum state of the black hole and its radiation is relatively un-complex
 . I will trace this computational difficulty to a geometric obstruction in
  the Einstein-Rosen bridge connecting the black hole and its radiation. In
 spired by tensor network models\, I will present a conjecture that relates
  the computational hardness of distilling information to geometric feature
 s of the wormhole - specifically to the exponential of the difference in g
 eneralized entropies between the two non-minimal quantum extremal surfaces
  that constitute the obstruction. Due to its shape\, this obstruction was 
 dubbed "Python's Lunch"\, in analogy to the reptile's postprandial bulge.\
