Teleportation

[Semnae]

Yes! They have done it! It's actually old news. The article was published in 2007, but it's the first I've heard about it. 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.

i'll start celebrating when i get a tardis.

Don't get too excited over what can be done by quantum physicians. 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.

i'd start clapping when they teleport a banana and its still edible, i mean *cough* steins;gate *cough*.

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

Well green jelly is edible! lol

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.

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.

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.

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.

Even if teleportation of living objects never happens, the idea of ordering something from Amazon and having it arrive in on my teleport pad in an hour or two is tantalizing.

Don't black holes teleport stuff all the time by string theory?

Hopefully before they invent teleporters we will have replicators and be able to pirate physical objects.

In theory, most commonly its thought that they "teleport" matter into another dimension. At least as best as I can remember.
At any rate, whatever goes through a blackhole is torn to pieces. The matter comes out, but thats it; the matter.

The practical application of this will be in communication. Communication to just the other side of the planet here can take several seconds (those who watch world news will have seen this), but communicating to Mars takes several minutes. I think its applications will be in low latency communication.

Indeed, then we could actually download cars...

Well, we DO have that 3D printer technology. It's a start, at least.
