quantum teleportation
I watched the movie “Timeline” tonight – hired on dvd – a fun action movie based on Michael Crichton’s novel of the same name. The story involves an archeologist who is transported back in time using the concept of breaking the 3D person down into packets of information and ‘faxing’ the data to another place – except a wormhole gets in the way and sends them back in time.
I thought I’d look at the purported principle and found that, for example, the ANU has actually achieved quantum teleportation of a few photons of light. It makes use of a principle known as the “Einstein-Podolsky-Rosen (EPR) correlation” or “entanglement” to impart information (spin) from one particle to another. The folks at IBM manage to explain it quite well in this site at www.research.ibm.com/quantuminfo/teleportation/
Fascinating concept, but I think I might wait a while before giving it a whirl…
