• Abstract: A theory of quantum gravity is expected to change profoundly our understanding of black holes. Quantum theory has already shown, as a first approximation, that a black hole slowly evaporates. Non-perturbative quantum gravity also predicts that such an object could metamorphose into a white hole, its time-reverse. In this thesis, we study the foundations of such a scenario and propose a mathematical model that includes the phenomenon of evaporation.

  In quantum gravity theory, a state-dependent gravitational potential introduces nonlinearity into the state evolution. The formalism for understanding the continuous quantum measurement process on the quantum state has been previously discussed using the Schr"odinger picture. In this work, an equivalent formalism using the Heisenberg picture is developed and applied to the analysis of two optomechanical experiment protocols.

• 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.

  I explain how black hole complementarity provides a framework to articulate how quantum characterizations of black holes can remain consistent despite the information paradox. I point out that there are two ways to cash out the notion of consistency in play here: an operational notion and a descriptive notion.

• A dialog on the fate of information in black hole evaporation [77.34726150561087]
  We present two alternative perspectives for the resolution of Hawking's information puzzle in black hole evaporation. One of them is the central role played by the existence of the interior singularity that we expect to be replaced by a more fundamental quantum gravity formulation. Both views rely on the notion that the standard effective quantum field theoretic perspective would require some deep modifications.

• Black Holes Decohere Quantum Superpositions [0.0]
  We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence of the superposition. This occurs because, in effect, the gravitational field of the body radiates soft gravitons into the black hole, allowing the black hole to acquire "which path" information about the superposition.

  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 report a fermionic lattice-model-type realization of an analogue black hole by using a chain of 10 superconducting transmon qubits with interactions mediated by 9 transmon-type tunable couplers. The quantum walks of quasi-particle in the curved spacetime reflect the gravitational effect near the black hole, resulting in the behaviour of stimulated Hawking radiation.

• What can we learn about islands and state paradox from quantum information theory? [10.24376036299883]
  We show that the Page curve can still be realized even if information is lost and the information paradox can be attributed to the measurement problem. Though speculative, the similarities between the black hole information problem and the measurement problem may suggest some link in the origins of the two fundamental issues of distant fields.
