About non-classical gravitational states

TL;DR

This paper explores the properties of a highly-quantum gravitational field state created by superposing classical configurations, using a spatial distance operator to analyze the system.

Contribution

It introduces a novel approach to studying quantum gravitational states through a spatial distance operator among macroscopic observers.

Findings

Expectation values reveal unique quantum properties of gravitational superpositions.

The framework provides insights into the structure of non-classical gravitational states.

Abstract

Take the gravitational field, a number of macroscopic observers and put them in a highly-quantum state, made by a coherent superposition of different classical configurations. How would that look like? I try to study this system by introducing a spatial distance operator among the observers and looking at the properties of its expectation values.
