Diagnosing collisions in the interior of a wormhole

TL;DR

This paper proposes a method for diagnosing collisions inside a wormhole connecting two black holes by analyzing a specific six-point correlation function in the entangled quantum circuit, allowing exterior observers to detect interior events.

Contribution

It introduces a novel approach linking quantum circuit overlaps to wormhole interior collisions, enabling external diagnosis without entering the black holes.

Findings

Overlap in quantum circuit correlates with collision detection inside wormhole

Six-point correlation function quantifies interior collision events

Exterior observers can diagnose interior interactions remotely

Abstract

Two distant black holes can be connected in the interior through a wormhole. Such a wormhole has been interpreted as an entangled state shared between two exterior regions. If Alice and Bob send signals into each of the black holes, they can meet in the interior. In this letter, we interpret this meeting in terms of the quantum circuit that prepares the entangled state: Alice and Bob sending signals creates growing perturbations in the circuit, whose overlap represents their meeting inside the wormhole. We argue that such overlap in the circuit is quantified by a particular six-point correlation function. Therefore, exterior observers in possession of the entangled qubits can use this correlation function to diagnose the collision in the interior without having to jump in themselves.
