Recent progress on the black hole information paradox has succeeded in reconstructing Page curves compatible with unitary evolution. The formula of generalized entropy derived from the gravitational path integration, nevertheless, does not provide concrete insight on how the information comes out from the black hole given that the state of the radiation seems to follow what was given by Hawking. In this paper, we provide a quantum informational interpretation of entanglement islands and draw… Expand

Quantum information cannot be completely hidden in correlations: implications for the black-hole information paradox.
TLDR
It is shown that the black-hole information paradox becomes more severe, even for cosmologically sized black holes, and either unitarity or Hawking's semiclassical predictions must break down. Expand
Entanglement swapping in black holes: restoring predictability
Hawking's black hole evaporation process suggests that we may need to choose between quantum unitarity and other basic physical principles such as no-signalling, entanglement monogamy, and theExpand
Black holes as mirrors: Quantum information in random subsystems
We study information retrieval from evaporating black holes, assuming that the internal dynamics of a black hole is unitary and rapidly mixing, and assuming that the retriever has unlimited controlExpand
A strong no-go theorem on the Wigner’s friend paradox
Does quantum theory apply at all scales, including that of observers? New light on this fundamental question has recently been shed through a resurgence of interest in the long-standing Wigner’sExpand
Unitarity of black hole evaporation in final-state projection models
A bstractAlmheiri et al. have emphasized that otherwise reasonable beliefs about black hole evaporation are incompatible with the monogamy of quantum entanglement, a general property of quantumExpand
Island may not save the information paradox of Liouville black holes
By using the quantum extremal island formula, we perform a simple calculation of the generalized entanglement entropy of Hawking radiation from the two dimensional Liouville black hole. No reasonableExpand
Black Hole Remnants and the Information Loss Paradox
Abstract Forty years after the discovery of Hawking radiation, its exact nature remains elusive. If Hawking radiation does not carry any information out from the ever shrinking black hole, it seemsExpand
Islands and Page curves of Reissner-Nordström black holes
We apply the recently proposed quantum extremal surface construction to calculate the Page curve of the eternal Reissner-Nordstrom black holes in four dimensions ignoring the backreaction and theExpand
Replica wormholes and the black hole interior
Recent work has shown how to obtain the Page curve of an evaporating black hole from holographic computations of entanglement entropy. We show how these computations can be justified using theExpand
Observations of Hawking radiation: the Page curve and baby universes
We reformulate recent insights into black hole information in a manner emphasizing operationally-defined notions of entropy, Lorentz-signature descriptions, and asymptotically flat spacetimes. WithExpand
