Resolution to the firewall paradox: The black hole information paradox and highly squeezed interior quantum fluctuations

TL;DR

The paper proposes that decoherence of infalling particles near the singularity resolves the black hole firewall paradox, avoiding the need for firewalls and preserving the equivalence principle.

Contribution

It introduces a decoherence-based mechanism for entanglement loss near the singularity, offering a novel resolution to the black hole information paradox without firewalls.

Findings

Decoherence occurs as infalling particles approach the singularity.

Loss of entanglement eliminates the need for firewalls.

The approach preserves the equivalence principle.

Abstract

Almheiri, Marolf, Polchinski, and Sully argued that, for a consistent black hole evaporation process, the horizon of a sufficiently old black hole should be replaced by a "firewall" at which an infalling observer burns up, which obviously leads to the violation of the equivalence principle. We propose that once the infalling partner of an outgoing Hawking particle approaches a black hole singularity, it experiences decoherence and the loss of its entanglement with the outgoing Hawking particle. This implies we would no longer need firewalls to avoid the black hole information paradox.
