Caltech researchers have demonstrated that a form of quantum 'sleight of hand' can be use to retrieve information on a particle's spin from a black hole.
The 'qubit' of information can be pulled back from the abyss due to entanglement between the black hole
and escaping particles called Hawking radiation (illustrated)

Black holes are the gluttons of the universe. Once matter passes their event horizon, also known as the point of no return, nothing can escape, not even light - or so we may think. Scientists at the California Institute of Technology now think it is possible to bring back information from the brink of existence one particle at a time, using a strange quantum trick. In particular, the researchers propose that 'quantum teleportation' could be the key to retrieving information from the yawning mouth of a black hole.
