Entropic Entanglement: Information Prison Break

TL;DR

This paper proposes a modification to local quantum field theory near black hole horizons that allows quantum information to escape via Hawking radiation while maintaining unitarity, and explores implications for black hole thermodynamics.

Contribution

It introduces a smooth, localized modification to LQFT at the horizon that enables information leakage and unitarity restoration without affecting infalling observers.

Findings

Quantum information can escape black holes through modified Hawking radiation.

Unitarity of black hole evolution can be restored with minimal impact on infalling observers.

Black hole thermodynamics may be interpreted through entanglement entropy, leading to nonsingular horizon behavior.

Abstract

We argue certain nonviolent local quantum field theory (LQFT) modification considered at the global horizon ($r=2M$) of a static spherically-symmetric black hole can lead to adiabatic leakage of quantum information in the form of Hawking particles. The source of the modification is (i) smooth at $r=2M$ and (ii) rapidly vanishing at $r\gg2M$. Furthermore, we restore the unitary evolution by introducing extra quanta which departs slightly from the generic Hawking emission without changing the experience of an infalling observer (no drama). Also, we suggest that a possible interpretation of the Bekenstein-Hawking bound as entanglement entropy may yield a nonsingular dynamical horizon behavior described by black hole thermodynamics. Hence by treating gravity as a field theory, and considering its coupling to the matter fields in the Minkowski vacuum, we derive the conjectured fluctuations of the background geometry of a black hole.
