“Recently, researchers at the Swiss Federal Institute of Technology in Zurich (ETHZ) used entanglement to teleport information across a quarter inch. That sounds easy. After all, the internet sends information thousands of miles in fractions of a second. But this time, the information wasn’t carried through the intervening space. Quantum computers are still only theoretical, but if engineering catches up with theory, then they could process enormously large datasets with blinding speed. This could make extraordinary things possible – even time travel, at least according to one hypothesis.”
