- 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.

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 that there are computations on $n$ qubits which cannot be implemented inside of black holes with entropy less than $O(2n)$.
We argue computations happening inside the black hole must be implementable in a programmable quantum processor.

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 use a driven-dissipative quantum fluid of microcavity polaritons as an analog model of a quantum field theory on a black-hole spacetime.
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.

We introduce an operational way to distinguish between the overall shift in the pulse wavepacket and its genuine deformation after propagation.
We then apply our technique to quantum states of photons that are coherent in the frequency degree of freedom.
We find that the quantum coherence initially present can enhance the deformation induced by propagation in a curved background.
