“The idea is not that the physical object is teleported but the information that describes it. This can then be applied to a similar object in a new location which effectively takes on the new identity.”
I’m an economist not a physicist but this doesn’t sound like teleportation to me. Rather it is the transmission of information not the transmission of an object.
Will someone more enlightened inform an ignorant economist what I’m missing?
I take it as an advanced copy of something.
I could inform you, but I would have to charge you...
I believe you’re correct. Quantum entanglement allows 2 entangled particles to have the same “information” regardless of how far apart the objects are. I have no clue how or why it works, and am not sure anyone else does either - but it’s not teleportation in the Star Trek sense.
go to the Technology Review link I posted in my post 1, they have more explanation.
But basically something is in one place, then the same/or at least identical something appears at a different location, without it having actually having moved there by moving through the space between the two location.
Hi, I am here at point A.
Next I am calling for you from point B, without actually being observed on route from A to B.
Famously referred to as "spooky action at a distance."
Just think of it like Internet Porn.
There is a sleight of hand involved here. What is done is that the state vector (colloquially, and less correctly, called a "wave function" by some) of a photon at distance is entangled with the state vector of a nearby photon. By manipulating the state of the near photon, a change in the state of the remote photon occurs. Because photons (actually all quantum particles) are indistinguishable, the state change reflected in the remote photon is identical to the appearance of a "new" photon with the same state.
However, since an observer at distance cannot know the state of our "nearby" photon (which is remote from his point of view) without exchanging state descriptions with us, there is actually no information being transmitted until an ordinary radio transmission (or pony express rider, or some other conventional information process) actually verifies the content. Roughly, the particles "know" they have been changed ("spooky action at a distance," in Einstein's words) but this knowledge cannot do anyone any good until ordinary messages can be exchanged.
This is the position of orthodox physics. It is not controversial, although there are a few (actually respected) dissenters who claim information can be exchanged in this way. But they have never constructed an experiment that shows how.
This article http://en.wikipedia.org/wiki/Quantum_teleportation does not completely suck, even though it is from Wikipedia. If you are very interested, also have a look at the Einstein-Podolsky-Rosen Paradox which is the original paper that got people thinking about the question of quantum entanglement. Both of these articles are accessible to an intelligent layman. The article on the EPR paradox is the better of the two. Interestingly, Einstein, Podolsky, and Rosen believed their "paradox" would overthrow Quantum Mechanics.
They were mistaken; it is not a paradox. It is the way the universe actually behaves.
If you want to follow this rabbit quite far down the hole, the issue was resolved (to the current state of our knowledge) by Bell's Theorem. Have a look there if you are an economist with a decent mathematical background and some time.
But I have often thought the simplest way (ha, that's an oxymoron) to do such was gather all the information down to the subatomic structure of an object, transmit it and reconstruct a clone of the object elsewhere. IE: a clone
Maybe the original is destroyed as it is codified and the new code “creates” the “teleported” version. Can’t think of how why ecept for the fact that nothing is truly destroyed/created (other than wht God accomplished), but all springs from other forms and changes to other forms.
