# A Information-Theoretic View on Spacetime

## TL;DR

This paper explores the tension between unitarity, quantum information bounds, and the idea of spacetime composed of disconnected microscopic patches, using an information-theoretic approach.

## Contribution

It provides a quantitative analysis showing how unitarity and quantum information constraints challenge the notion of a patchwork spacetime at microscopic scales.

## Key findings

- Unitarity and quantum information bounds are in tension with disconnected microscopic patches.
- Quantitative analysis reveals constraints on spacetime structure from quantum principles.
- Supports a continuous or connected spacetime model at microscopic scales.

## Abstract

We argue in a quantitative way that the unitarity principle of quantum field theory together with the quantum information bound on correlation functions are in tension with a space which is made out of disconnected patches at microscopic scales.
