DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/IFQ/4
 /">A quantum circuit interpretation of evaporating black hole geometry</a>
 \nby Ying Zhao (IAS) as part of It from Qubit\n\n\nAbstract\nWhen Alice sh
 ares thermofield double with Bob\, her time evolution can make the wormhol
 e grow. We identify different kinds of operations Alice can do as being re
 sponsible for the growth of different parts of spacetime and see how it fi
 ts together with subregion duality. With this\, we give a quantum circuit 
 interpretation of evaporating black hole geometry. We make an analogy betw
 een the appearance of island for evaporating black hole and the transition
  from two-sided to one-sided black hole in the familiar example of perturb
 ed thermofield double. If Alice perturbs thermofield double and waits for 
 scrambling time\, she will have a one-sided black hole with interior of he
 r own. We argue that by similar mechanism the radiation gets access to the
  interior (island forms) after Page time. The growth of the island happens
  as a result of the constant transitions from two-sided to one-sided black
  holes.\n
