So, apparently they've got the success rate way, way up with this kind of thing, although the process involves electrons "trapped in diamonds at extremely low temperature". Still, one step closer...

RELEVANT EVE LORE FACTOID: Quantum entanglement, used in this 'teleportation', is the way our "fluid router" communications function in EVE lore. This is why - in addition to being instantaneous despite vast stellar distances - it is virtually impossible to 'jam' our communications: The entanglement effectively functions 'around' rather than 'through' the space between two points; any noise between those two points is irrelevant so long as the entangled link holds up.

Good. Maybe then i wont lag when i play games with my friends online.

Still, this news gives me a massive nerd hard on for all forms of tech.

From my experience the overwhelming majority of Teleportation technologies result in radiation so horrible that if something living does make it through it won't last long. The ONLY real way to make the tech work is to use quantum methods of traversal.
Even then you are dealing with factors such as temperature change and sever psychological trauma for anybody not specifically conditioned for such a thing.

It should be noted that we have no idea how to condition or prepare somebody for that yet.

Maybe we should work on moving from teleporting leptons to atoms, and eventually molecules, before we start assuming there will be repercussions preventing safe teleportation of living creatures.

...and now, a few fugly facts:

- the "outgoing" qubit is destroyed in the process of reading, and so each pair only can be used once
- quantum pairs are created together, then they are physically seperated
- albeit a qubit haves endless potential states, only one of them can be transmitted at a time (and then the qubit is destroyed)

Q: Should we be worried? A: Nope. (...) Worry a lot if Fozzie, Masterplan, Rise, Veritas, Bettik, Ytterbium, Scarpia, Arrow, or even Greyscale leaves. Worry a little if Punkturis, karkur, SoniClover, Affinity, Goliath, or Xhagen leaves.

I would "entangle" the other part of the space with my own state so I would be in two places in one time, shearing my state with two parts of space, then I would "extangle" the state that is here, and I would leave intact the other state, would it be a teleportation?
Unfortunately its a Sci-fi, not an actual science. Sad

Information send to the other part of space can be send only with a light speed, and the facility to entangle the other me would need less than light speed to move there.

First teleportation via carrying atoms over a radio wave, then laser and now diamonds.
This all seems pretty primitive to me, I'll wait for wormhole technology.

Teleporters are fine and dandy in theory, but a replicator has more practical applications and it can pretty much double for a pseudo-teleporter (as far as practical//pragmatic aspects are concerned anyway).

In virtual reality you can teleport anything anywhere, you are making up the rules, but in real, the rules rule you. Maybe in Matrix we would be able to make and do anything. Lol

If I found out we lived in the Matrix, I would learn how to work the thing and then happily stay inside. After a quick look at what lies on the outside, I have to believe these parasitic robots are pretty benevolent. Guess it's not really parasitism if I'm willing, eh?

But once it had arrived, it could remain in place and perform more entanglements.

Can you even entangle particles from a distance? I always thought you have to create them entangled and then move them apart from each other.

You might have to operate both ends, but it is this "entanglement" which demonstrates really clearly that things that seem far apart by our observations sometimes or perhaps always are actually in direct contact with each other.

Edit: I forgot to mention: This is a fascinating way to look at entanglement. It never occured to me! /Edit

Well, on that submicroscopic level I already have a hard time grasping what "direct contact" means.
I mean, you don't have surfaces touching each other anymore, right? You have waveforms interferring with each other and forces between particles, but I really don't know what "contact" can mean in that context besides "being in close proximity" and maybe "short ranging forces dominate", whatever those forces might be (I'm not really that knowledgable in physics.).

That said, if you can make use of that "direct contact" property to entangle particles with each other which look distant to our observations, then why can't you use that same property to transmit information directly?

But, back to entanglement: It seems I already don't understand something fundamental about entanglement. What I knew as entanglement so far were pairs of particles which are guaranteed to have "opposite" values in a certain property. For example polarization for photons.. or spin of electrons.
This manifests when you observe/measure one of the particle pair. In the moment of measurement you collapse the wave function of that particle and it changes from being in a superposition of all possible states to having one definite state, for example "spin up" in the measured direction. With entangled particles that also means that the wave function of the partner particle collapses in the same instant, so that it is assuming the complementary value in that measured property.
That doesn't help in transmitting information though, as you can't notice any change without measurement, so you can't magically know that the particle on the other end was measured now.

If you could -change- one of those properties in an entangled particle, so that the partner particle would follow through with the complementary change, that'd be nice for transmitting information, but I didn't know that was possible.

.. what a long post to say "I don't know how it works" .. haha.

I don't know how it works, either.

One helpful tidbit can be to learn to accept that there are no solid surfaces anywhere, only fields of exponentially diminishing potential from an apparent but illusory epicenter. When you touch a "surface", there is a range within which you are able to press--more pressure can put your finger further into the surface. The amount it goes in is just so tiny we cannot come close to perceiving it. But you can play with a much "weaker" repulsive force, that is, a repulsive force that diminishes at a much lower rate with distance from the center. When you press equal poles of two magnets together, they repel each other, and the closer you press them, the stronger the repulsive force becomes. It's the same thing as the surfaces around you, but on a larger scale.

Yes, that part I get. But I don't understand how you'd define "contact" under those circumstances. :)

The magnets are always in contact with each other. They are affecting one another. That's what contact is. If I push you or the magnet repels another magnet, it's a very similar effect.

But if it is "just" that, then you'd have to say that, for example, our milky way and the andromeda galaxis are in contact, too, because they affect each other due to gravity.
Maybe an extreme example, but that can't very well be the sort of contact you meant with regards to entanglement. Because, going back to magnets, when repelling one magnet with the other, the repelling force doesn't take effect immediately, as far as I know. If you move the one magnet, the other one "feels" the change in the magnetic field a miniscule amount of time later, because the changes of the magnetic field don't travel faster than with the speed of light.

That was the reason for my question originally, with regards to your statement about the possible direct contact between entangled particles before. What is direct contact in that case?

Originally I thought you might mean that we only perceive them very distant from each other, while they may be in fact very close to each other, in a way which (so far) is outside our observation capabilities. Different dimensions or such fancy things. Who knows, maybe those two particles are actually only one particle and we just can't see this fact.
Ok ok, that's a little crazy now, haha.
