That’s a question my friends and family ask me (jokingly) on a regular basis, given that my graduate studies involve quantum mechanics and given that “quantum teleportation” is perhaps second in popularity only to “exoplanets” as a topic for popular science writing.
Seriously, there are so many articles about it. And that’s not a bad thing: I love anything that gives more exposure to the genuine awesomeness of quantum physics. Plus the field is undeniably hot right now: just as it seems like a new exoplanet is discovered every month, so to are different teams of physicists seemingly breaking teleportation records for size and distance.
But despite the current media exposure, the idea is, I think, still poorly understood. True, most folks are all well-informed enough by now to understand that when physicists say “quantum teleportation,” they don’t intend you to imagine them saying it in a Scottish accent, because just about every article on the subject dutifully clarifies that this ain’t quite the same thing as that shimmery trick Scotty does on “Star Trek.” But while everyone’s clear on what quantum teleportation is not, understanding just what it is can be a mite more difficult.
