Well green jelly is edible! lol

In this experiment, a photon was teleported 144km, to another island. This hasn't been tried on anything more complicated than photons, but just the idea of being able to teleport matter is very exciting.

They've been doing that for almost 20 years now. Teleporting photons isn't special. I read about successful teleportation experiments over large distances back when I was in middle school, that took place years prior. I haven't read that article, but it could just be the furthest, or a photon of a particularly high energy or something.

Quantum particles can be at more than one place at a time or nowhere or even everywhere (in theory). What's possible at this level isn't necessarily possible on a macroscopic level.

Why is that? We are all made of quantum particles after all. Why are these properties lost as things get bigger?

To answer that question, to keep a single photon entangled is diffifucult. When observed it wants to stop being a wave and become a particle (not quite true, but its to get a point across). AS you know everything is both a wave and a particle, however, everything we interact with seems to act like a particle. This is because the wave has "collapsed" to a single value. Keeping large things in a quentum state is incredible difficult. In fact, it wasn't until last decade that any macroscopic object exibited quantum properties. Its not impossible to make a large scale teleporter, but its pretty far off. You have to keep the outside world from interacting with whatever is being teleported for the entanglement breaks.

Ixarku:
I vaguely recall that one of those Discovery channel science shows said that the amount of information necessary to teleport & reconstruct a person was the equivalent of the data contained on a pile of CD disks in a cube 10 miles long per side.  Teleportation at a macro level, FTL, wormholes, and all of those other wonderful sci-fi ideas aren't going to become a reality within our lifetimes.  More power to the scientists researching these things, I say, but I'm also not holding my breath waiting for this sort of future tech!

Honestly, I don't think the data processing is going to be the hardest part. I think its going to be the entangling process.

Soryon:
This is by no means a new phenomena, but its awesome that they are still toying with it. I fail to get too excited hearing this (actually ready that a while ago) but I am really glad that they aren't giving up. Even if they dont manage to figure out how to teleport things on a macroscopic level, who knows what we might learn on the way. I love it when they dont give up.

Everything starts somewhere.
