I-If i can teleport special pizza from italy to my home via quantum teleportation then GAME OVER YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH
[QUOTE=bravehat;22068537]Ok, for example we take quantum morse code.
State A = .
State B = -
Since we have one particle, if it's in state B we know the message being sent is from state A
So we see - so we know what is being sent is .
:v: See it's fairly useful, just gonna have to go back to Morse code for interplanetary stuff.[/QUOTE]
But the problem is you can't control [I]how[/I] the waveform collapses.
This part is the problem :

You can't choose if you're sending a line or a dot.
Boy, do I love it when scientists rip Causality and the Laws of Physics a new one. :v:

Well by fucking god we'll find a way!! :science:
This seems like an awesome thing that I cannot even begin to understand.
[QUOTE=Eudoxia;22066864]Oh my Sagan, fucking history![/QUOTE]
A man is your god?
Yeah fuck you, religion, what new creations do you have?
Nothing?
Fuck your shit go to the naughty corner.
Holy fuck.
[QUOTE=Deweze;22069194]A man is your god?[/QUOTE]
I am my own god, so why can't someone worship one of the greatest scientific minds of our time?
[QUOTE=leontodd;22066905]I hear articles like this daily and nothing ever comes out of it.[/QUOTE]
Invention =/= instant way of application.
While there is always leaps and bounds in technological advancement, creating a practical purpose for them is alot more time consuming. Once a purpose has been found and prototypes perfected, it then has to be commercially viable and marketable. If the Higgs Bonson is discovered, the world won't change unless they can do something practical with it.
It took 90 years for a telephone to be a common object, but it changed the world.
[QUOTE=Eudoxia;22068015]What about violations of Causality?[/QUOTE]
You're not getting it. NOTHING is moving- including energy.
FTL communications is one step closer.
This is the quantum communicator in Mass Effect 2. Not so much the standard sci-fi device.
I love reading about this sort of stuff, it might be "nerdy" but it's damned incredible stuff
[QUOTE=Eudoxia;22066891]This is it. Human progress is such an amazing thing.
*Single manly tear*
If the rate at which we progress continues to increase, the future may be closer than we think.[/QUOTE]
But then we're also that much closer to killing each other off until no one is left :smith:
I mean, it seems feasible that this could very well allow us to instantly transfer information over incredibly vast distances. I see the argument that it violates theory of relativity (even though I disagree), but how does it violate causality?
[QUOTE=Eudoxia;22067003]Okay so it doesn't violate relativity because it doesn't travel FTL, it just gets teleported.
What about Causality? You get see send information faster-than-light so... Oh wait I think I got it wrong. Bleh.[/QUOTE]
Quantum teleportation DOES violate the speed of light, and thus probably causality.

Even Einstein thought it was... 'spooky'.
As neat as this is and its potential to advance the human race, it's probably just going to be turned into a weapon as soon as possible.
[QUOTE=Eudoxia;22068285]Oh I see.
And about this observation, I keep hearing people saying 'mental powers' can affect particles.
When you say 'observation', is is the person/machine that observes it or the phyisical method of observation (Some machine with instruments measuring stuff) that affects the particles?[/QUOTE]
Observation is similar to stopping a spinning dial and seeing what it lands on. The whole "mental powers" thing is some attempt by a bunch of pseudosciences to hijack quantum mechanics and turn it into some new age spiritualism.
Why is is that stories like this come up constantly, and yet nothing useful comes from it except theoretical knowledge?
Fucking awesome!
Sure, this is "Oh my bloody Feynman" awesome, but I'm waiting with the party until we can bend spacetime.
To explain Quantum Physics to the layman, I present to you Professor Hubert J. Farnsworth.

That should help anyone who doesn't understand.
[QUOTE=its shortie;22066872]Latency of 0ms anyone? :smug:[/QUOTE]
One day, one day we may be able to achieve lagless video gaming.
No need for client-side prediction, amazing shit could be done :monocle:
Oh wow I never even thought about teleporting for communications.
[QUOTE=its shortie;22066872]Latency of 0ms anyone? :smug:[/QUOTE]
With a fidelity of 89%, you'd get a lot of packet drops.
People are out there teleporting things and im on my computer spamming MW2 quotes on chatrooms?
Couldn't this be used for moving photons at speeds faster than the speed of light? Like, if you have two photons, both bonded to each other and both several light years apart. If you spin one photon, it wont spin faster than the speed of light, but since the second photon is several light years away and has to go in circles around you and the first photon it will travel faster than the speed of light.
