Collision in the interior of wormhole

TL;DR

This paper explores the collision of perturbations inside a Schwarzschild wormhole, linking gravitational interactions with quantum circuit models to understand the meeting of entangled black hole interiors.

Contribution

It introduces a novel interpretation of interior collisions in wormholes using quantum circuit analysis, connecting gravity and quantum information.

Findings

Perturbations in the circuit correspond to black hole interior interactions.

Overlap of perturbations models the meeting point of Alice and Bob.

Post-collision region stores unaffected quantum gates.

Abstract

The Schwarzschild wormhole has been interpreted as an entangled state. If Alice and Bob fall into each of the black hole, they can meet in the interior. We interpret this meeting in terms of the quantum circuit that prepares the entangled state. Alice and Bob create growing perturbations in the circuit, and we argue that the overlap of these perturbations represents their meeting. We compare the gravity picture with circuit analysis, and identify the post-collision region as the region storing the gates that are not affected by any of the perturbations.
