Baby Universes from Thermal Pure States in SYK
Martin Sasieta, Brian Swingle, Alejandro Vilar López
We construct a simple two-dimensional holographic model of a closed "baby" universe. The baby universe spacetime originates from the black hole interior in Jackiw-Teitelboim (JT) g…
Twirled Perfect Tensor Networks: Computationally covariant holographic tensor networks
Gurbir Arora, Matthew Headrick, Albion Lawrence +3
We define a novel class of tensor networks motivated by the Python's Lunch Conjecture (PLC) in local tensor network models of the black hole interior. We start from the observation…
Preparing High-Fidelity Thermofield Double States
Brian J. J. Khor, Nadie LiTenn, Martin Sasieta +1
A major promise of quantum computers is the controlled preparation of many-body quantum states beyond the reach of efficient classical computation. Among the most important targets…
ER for typical EPR
Javier M. Magan, Martin Sasieta, Brian Swingle
What do the typical entangled states of two black holes look like? Do they contain semiclassical interiors? We approach these questions constructively, providing ensembles of state…
The Baby Universe is Fine and the CFT Knows It: On Holography for Closed Universes
Stefano Antonini, Pratik Rath, Martin Sasieta +2
Big bang/big crunch closed universes can be realized in AdS/CFT, even though they lack asymptotically AdS boundaries. With enough bulk entanglement, the bulk Hilbert space of a clo…
Random Circuits in the Black Hole Interior
Javier M. Magan, Martin Sasieta, Brian Swingle
In this paper, we present a quantitative holographic relation between a microscopic measure of randomness and the geometric length of the wormhole in the black hole interior. To th…
