Excerpt:


Information escapes from black holes via Hawking radiation, so it should be possible to capture it and use it to reconstruct what fell in: if given time longer than the age of the universe. However, if information is scrambled rapidly when it falls in, it may be possible to resurrect it by capturing Hawking radiation from entangled qubits. Physicists confirmed scrambling in a quantum computer, based on predictions by theorists.

This is a schematic of the black hole information paradox. Alice drops a qubit into a black hole and asks whether Bob can reconstruct the qubit using only the outgoing Hawking radiation.
