We identify different kinds of operations Alice can do as being responsib le for the growth of different parts of spacetime and see how it fits toge ther with subregion duality. With this\, we give a quantum circuit interpr etation of evaporating black hole geometry. We make an analogy between the appearance of island for evaporating black hole and the transition from t wo-sided to one-sided black hole in the familiar example of perturbed ther mofield double. If Alice perturbs thermofield double and waits for scrambl ing time\, she will have a one-sided black hole with interior of her own. We argue that by similar mechanism the radiation gets access to the interi or (island forms) after Page time. The growth of the island happens as a r esult of the constant transitions from two-sided to one-sided black holes. \n LOCATION:https://researchseminars.org/talk/IFQ/4/ END:VEVENT END:VCALENDAR
