Chinese scientists say they have "teleported" a photon particle from the ground to a satellite orbiting 1,400km (870 miles) away.
For many, however, teleportation evokes something much more exotic. Is a world previously confined to science fiction now becoming reality?
Well, sort of. But we are not likely to be beaming ourselves to the office or a beach in the Bahamas anytime soon. Sorry.
How does it work?
Simply put, teleportation is transmitting the state of a thing rather than sending the thing itself.
Some physicists give the example of a fax machine - it sends information about the marks on a piece of paper rather than the paper itself. The receiving fax machine gets the information and applies it to raw material in the form of paper that is already there.
