Ok, as some of you might know, I'm sad and study physics, mathematics and chemisty at A level... So the following interests me a lot, and it might interest you (it's pretty amazing):

Dont worry mini.

I took a level maths, further maths, physics, chemistry(chemistry was just as level) and media

Thats pretty awesome, have you got any other information on it?

Yeah im doing further maths as well ;) C3 and C4 are lame!

I think that's pretty much all, I heard about quantum entaglement a few months ago, this is kind of a new break through.

Eeh there seem to be text in the link, you dont have a youtube link or something?? Sorry im just a bit drunk. :lol:

c3 and c4 were fine for me , statistics 1 and 2 were hell :D

that's... pretty damn cool, actually

how did they manage to prove that they were directly related, and it wasn't just co-incidence?

They have done tests over smaller distances, and I'm pretty sure they have to do something to make the photons/electrons entangle, and they change at exactly the same time, if it were coincidence then I really doubt it would be at exactly the same time and both would end up with exactly the same data.

Hasn't this very article already been posted on this forum?

I had a great deja vu experience when reading this thread.

Pretty old news though.
The first papers on this topic were released in 1997 and practically the same expirement has been done in Vienna several times since 2000. (In the first one they teleported the quantum state of photons through a tunnel under the Donau)
The latest experiment of those scientists was to use this phenomenon for quantumn encryption between 2 islands in the canaries, over 140km apart.


That's also the reason why Gordon Freeman studied quantumn teleportation in Vienna (after he was at MIT).

They don't actually transmit any information, so it's not in violation of general relativity.

Wikipedia says otherwise: http://en.wikipedia.org/wiki/Gordon_Freeman

After observing a series of teleportation experiments conducted by the Institute for Experimental Physics in Innsbruck, Austria, the transmission of matter became Gordon's obsession.

They made 3 different kinds of quantum encryption as tests, and 2 of them got hacked straight away without the people sending information knowing about it (although I think hacking them was rather impractical), since the main defence was that the photons going down the fibre optics got disturbed if someone tried to copy the data, so then the system just changed the key and away it went again, until another disturbance and so on...

Yeah, I can't find a good article on it on a quick search, but supposedly they did 144km, I think they are going to try one from space next. Should be interesting.
