DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGHOLQI/4/">
 Finding Pythons in Unexpected Places</a>\nby Geoffrey Penington (Berkeley 
 University) as part of Quantum Gravity and All of That\n\n\nAbstract\nWe a
 rgue that novel (highly nonclassical) quantum extremal surfaces play a cru
 cial role in reconstructing the black hole interior even for isolated\, si
 ngle-sided\, non-evaporating black holes (i.e. with\nno auxiliary reservoi
 r). Specifically\, any code subspace where interior\noutgoing modes can be
  excited will have a quantum extremal surface in\nits maximally mixed stat
 e. We argue that as a result\, reconstruction of\ninterior outgoing modes 
 is always exponentially complex. Our\nconstruction provides evidence in fa
 vor of a strong Python's lunch\nproposal: that nonminimal quantum extremal
  surfaces are the exclusive\nsource of exponential complexity in the holog
 raphic dictionary. We also\ncomment on the relevance of these quantum extr
 emal surfaces to the\ngeometrization of state dependence in the typicality
  arguments for\nfirewalls.\n
