Hayden–Preskill thought experiment
E590897
The Hayden–Preskill thought experiment is a theoretical scenario in black hole physics that explores how quickly information thrown into a black hole can be recovered from its Hawking radiation, with implications for the black hole information paradox and quantum information scrambling.
