    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.

    Demonstration of scrambling in quantum computer shows how to resurrect ‘lost’ information. Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these bizarre objects.

    Scrambling is what happens when matter disappears inside a black hole...
