The Smallest Interacting Universe

Modjtaba Shokrian Zini, Adam R. Brown, Michael Freedman

The co-emergence of locality between the Hamiltonian and initial state of the universe is studied in a simple toy model. We hypothesize a fundamental loss functional for the combin…

A Quantum Complexity Lowerbound from Differential Geometry

Adam R. Brown

The Bishop-Gromov bound -- a cousin of the focusing lemmas that Hawking and Penrose used to prove their black hole singularity theorems -- is a differential geometry result that up…

Universality in long-distance geometry and quantum complexity

Adam R. Brown, Michael H. Freedman, Henry W. Lin +1

In physics, two systems that radically differ at short scales can exhibit strikingly similar macroscopic behaviour: they are part of the same long-distance universality class. Here…

Quantum Gravity in the Lab: Teleportation by Size and Traversable Wormholes, Part II

Sepehr Nezami, Henry W. Lin, Adam R. Brown +6

In [1] we discussed how quantum gravity may be simulated using quantum devices and gave a specific proposal -- teleportation by size and the phenomenon of size-winding. Here we ela…

Playing Pool with : from Bouncing Billiards to Quantum Search

Adam R. Brown

In "Playing Pool with ", Galperin invented an extraordinary method to learn the digits of by counting the collisions of billiard balls. Here I demonstrate an exact isomorphi…

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…
