Falling into an evaporating black hole results in information recovery via Hawking radiation
Multiple studies support the view that information falling into an evaporating black hole is eventually recovered via correlations and entanglement in Hawking radiation, preserving quantum unitarity.
The retrieved literature contains multiple theoretical papers demonstrating mechanisms—such as Hawking radiation correlations, tunneling models, and the island formula—by which quantum information is preserved and recovered during black hole evaporation, supporting the claim.

Paper 0 concludes that information is leaked out hidden in the correlations of Hawking radiation, preserving quantum unitarity.

Paper 2 finds that for evaporating black holes, the fidelity of quantum information recovery grows as entanglement between parts of the radiation becomes extensive.

Paper 6 demonstrates that information can escape an evaporating black hole via timelike channels as the black hole shrinks.

Paper 7 shows that black hole evaporation is governed by a time-dependent Schrödinger equation, confirming that the process is unitary and information is preserved.

Paper 11 applies the island prescription to show that including islands after the Page time restores the Page curve and ensures information recovery.
