• Abstract: We extend previous efforts to quantify the entanglement generated in Hawking's evaporation process by including rotation and thermal environments (e.g. the cosmic microwave background). Both extensions are needed to describe real black holes in our universe. Leveraging techniques from Gaussian quantum information, we find that the black hole's ergoregion is an active source of quantum entanglement and that thermal environments drastically degrade entanglement generation. Our predictions are suitable to be tested in the lab using analogue platforms and also provide tools to assess the fate of quantum information for black holes in more generic settings.

• Page Time as a Transition of Information Channels: High-fidelity Information Retrieval for Radiating Black Holes [11.13371546439765]
  In this Letter, we demonstrate that this view can be relaxed in a new postselection model. We investigate information recoverability in a radiating black hole through the non-unitary dynamics that projects the randomly-selected modes from a scrambling unitary. We show that the model has the merit of producing the von Neumann entropy of black holes consistent with the island formula calculation. In this model the Page time gains a new interpretation as the transition point between two channels of information transmission when sufficient amounts of effective modes are annihilated inside the horizon.

  The non-isometric holographic model of the black hole interior stands out as a potential resolution of the long-standing black hole information puzzle. We show how Yoshida-Kitaev decoding strategy can be employed in the modified Hayden-Preskill protocol. This study would stimulate more interests to explore black hole information problem on the quantum processors.

• Stimulated Emission of Radiation and the Black Hole Information Problem [0.0]
  Black holes not only emit radiation spontaneously, but also respond to infalling matter and radiation by emitting approximate clones of those fields in a stimulated manner. I show how stimulated emission turns the black hole into an almost optimal quantum cloning machine. I speculate about possible observable consequences of stimulated emission of radiation in black holes.

  We show significant quantum information regarding the quantum state of the black hole prior to the Page time. By computing the quantum fidelity in a 2D boundary conformal field theory model of black hole evaporation, we demonstrate that an observer outside of an evaporating black hole may distinguish different black holes.

  Accelerating relativistic mirror has long been recognized as a viable setting where the physics mimics that of black hole Hawking radiation. Chen and Mourou proposed a novel method to realize such a system by traversing an ultra-intense laser through a plasma target with a decreasing density. An international AnaBHEL Collaboration has been formed with the objectives of observing the analog Hawking radiation and shedding light on the information loss paradox.

  Recently quantum information contained in Hawking radiation has been calculated, verifying a key aspect of the consistency of black hole evaporation with quantum mechanical unitarity. We review these developments and describe some of the deep open questions in this subject. These include the nature of the black hole interior, potential applications to quantum cosmology, the gravitational explanation of the fine structure of black holes, and the development of further connections to quantum information and laboratory quantum simulation.

We show that, in addition to the Hawking effect at the sonic horizon, quantum fluctuations may result in a sizeable stationary excitation of a quasi-normal mode of the field theory.
