Have you ever heard that astronauts and even air travellers age slower due to their speed? (see
http://en.wikipedia.org/wiki/Hafele?Keating_experiment). Clocks move slower when you move faster. If your twin brother takes a 15 hour flight he is about 47ns younger than you when he lands.
Instead of you and your brother, they could entangle a pair of photons, send one of them on a 15 hour flight. When it lands, that photon is now 47 nanoseconds in the past. They could then do a quantum teleportation experiment (
http://en.wikipedia.org/wiki/Quantum_teleportation), and if it works, would be I guess, time travel.
