Quantum Maximin Surfaces
Chris Akers, Netta Engelhardt, Geoff Penington +1
We formulate a quantum generalization of maximin surfaces and show that a quantum maximin surface is identical to the minimal quantum extremal surface, introduced in the EW prescri…

The Python's Lunch: geometric obstructions to decoding Hawking radiation
Adam R. Brown, Hrant Gharibyan, Geoff Penington +1
According to Harlow and Hayden [arXiv:1301.4504] the task of distilling information out of Hawking radiation appears to be computationally hard despite the fact that the quantum st…

Replica wormholes and the black hole interior
Geoff Penington, Stephen H. Shenker, Douglas Stanford +1
Recent work has shown how to obtain the Page curve of an evaporating black hole from holographic computations of entanglement entropy. We show how these computations can be justifi…
