Emergent Mixed States for Baby Universes and Black Holes
Jonah Kudler-Flam, Edward Witten
We examine the behavior of sequences of states in the large limit of AdS/CFT duality in cases in which the bulk duals involve baby universes or black holes. Such sequences gene…
Stringy algebras, stretched horizons, and quantum-connected wormholes
Aidan Herderschee, Jonah Kudler-Flam
While the supergravity limit of AdS/CFT has been extensively explored, the regime in which stringy dynamics dominate, characterized by the emergence of an infinite tower of higher-…
It costs nothing to teleport information into a black hole
Jonah Kudler-Flam, Geoff Penington
It is often claimed that adding a qubit to a black hole requires energy so that the extra Bekenstein-Hawking entropy can accommodate the qubit. In this essay,…
Absolute entropy and the observer's no-boundary state
Andreas Blommaert, Jonah Kudler-Flam, Erez Y. Urbach
We investigate the no-boundary proposal for closed universes with an observer. We argue that the observer's no-boundary state is the identity operator on the physical Hilbert space…
Vacua and infrared radiation in de Sitter quantum field theory
Jonah Kudler-Flam, Kartik Prabhu, Gautam Satishchandran
We analyze the asymptotic behavior of quantum fields and perturbative quantum gravity in de Sitter space. We show that the necessary and sufficient condition for the existence of a…
How to Minimize the Decoherence Caused by Black Holes
Daine L. Danielson, Jonah Kudler-Flam, Gautam Satishchandran +1
We consider an experimentalist, Alice, who creates a quantum superposition of a charged or massive body outside of a black hole (or, more generally, in the presence of a Killing ho…
