Aw , yes !
It would be awesome to go to wherever you want in 1 second
Oh, I feel like going to Hawaii
Actually, if what I'm gleaning from this article is accurate, then you are incorrect in this statement.
En ies that experience quantum entanglement do not obey any current known laws of physics (although they fit somewhat within special relativity. You could take two subatomic particles that are entangled, put them on opposite ends of the universe from each other, and they both instantly react to a change even if only one of them has been directly affected. This means that if both particles are on opposite sides of the US, or one is here and the other is next to Rigel, they both react instantly when one of them is acted upon by a particular force.

Theoretically, yes.
There's no way to know that for sure though, because we can't communicate the measurements FTL.
(iow, if Alice sends a tangled qubit to Bob, and Alice causes the bit to decohere by measuring it, there's no way for Alice to get the info from Bob FTL.)
Some awesome posts by DR, LnG, and basically everyone else in this thread. I didn't even ponder the effect quantum teleportation could have on the transfer of information - o, duh!
What an awe inspiring concept. Just think of communicating with an alien species galaxies away within a year or two of an eventual successful transfer of coded information; one whose advanced enough to understand FTL (or at least as fast as light) travel and could quickly (within years, max) communicate how to construct such devices ourselves. This could very well be the way we explore the universe - not through USS Enterprise clones, but through an undoubtedly already established universally spanning internet!
There's probably hundreds of races of intelligent, "benevolent" beings just waiting for relatively primitive races such as us to contact them so they can share their knowledge with us, just like we would then be doing for any other races ourselves.
Wow.

Exactly
But you don't have to communicate the measurements faster than light...
The Quantum Eraser experiment shows the "Spooky effect at a distance" quite clearly, and you don't need to communicate any measurements...
Well yes. (Speaking of which, I love that experiment. But if you want a REAL mindscrew, check the delayed choice quantum eraser...)
But I'm just saying, if you send qubit A to the moon and qubit B to Reno, Nevada, even if they both decohere in the same instant, there's no way for Alice and Bob to know for sure that they decohered instantaneously without some sort of confirmation, which must be passed along in some less-than-FTL manner. So for those specific instances where the decoherence occurs at distances (making the "Spooky Action" even spookier), there's no way to confirm instantaneously that it happened instantaneously.

By using a coincidence counter, the experimenters were able to isolate the entangled signal from the overwhelming photo-noise of the laboratory - recording only events where both signal and idler photons were detected.
When the experimenters looked only at the signal photons whose entangled idlers were detected at D1 or D2, they found an interference pattern.
However, when they looked at the signal photons whose entangled idlers were detected at D3 or similarly at D4, they found no interference.
This result is similar to that of the double slit experiment, since interference is observed when it is not known which slit the photon went through, while no interference is observed when the path is known.
However, what makes this experiment possibly astonishing is that, unlike in the classic double-slit experiment, the choice of whether to preserve or erase the which-path information of the idler need not be made until after the position of the signal photon has already been measured by D0.
There is never any which-path information determined directly for the photons that are detected at D0, yet detection of which-path information by D3 or D4 means that no interference pattern is observed in the corresponding subset of signal photons at D0.
The results from Kim, et al. have shown that whether the idler photon is detected at a detector that preserves its which-path information (D3 or D4) or a detector that erases its which-path information (D1 or D2) determines whether interference is seen at D0, even though the idler photon is not observed until after the signal photon arrives at D0 due to the shorter optical path for the latter.
Some have interpreted this result to mean that the delayed choice to observe or not observe the path of the idler photon will change the outcome of an event in the past. However, an interference pattern may only be observed after the idlers have been detected (i.e., at D1 or D2).
And here's a trippy idea based on the results of the Delayed Choice Quantum Eraser...

As an aside.... Dont want to derail my own thread.....
I think that if all the people from upstairs on this board came to this thread, their heads would explode while trying to wrap their heads around whats actually going on.
Thats not theoretical, BTW. Their brains would literally liquify and their eyeballs would explode. The only thing keeping them safe is their own ignorance.
I have no problem admiting that Im proud to have started this ultimate geek discussion.
admittedly, I dont understand half the stuff being talked about but I can somewhat grasp at it having at least a very basic understanding of quantum physics.... I can wrap my head around the idea, but dont ask me to give a good explanation.
please, let us continue onto the next point of discussion which will be in my very next post.

Nano-scale Transistor for Quantum Computation Processors
Published on April 21, 2011 at 8:27 AM
By Cameron Chai
A team of researchers at the University of Pittsburgh has developed a single-electron transistor called SketchSET, or sketch-based single-electron transistor to help build enhanced computer memories, electronic materials, and the quantum computer parts.
The research paper has appeared in Nature Nanotechnology and explains that the computer’s core component, an island measuring 1.5nm in diameter, can function with just one or two electrons. This feature would render the transistor applicable in ultradense memories and quantum processors. These devices could help address complicated issues.
Pitt's SketchSET
The nano-scale island could also function as a synthetic atom to create new artificial electronic materials including superconductors, says team leader Jeremy Levy, a professor of physics and astronomy in the School of Arts and Sciences. Levy collaborated with lead author and physics and astronomy graduate student Guanglei Cheng, besides physics and astronomy researchers Feng Bi, Daniela Bogorin, and Cheng Cen. The Pitt team collaborated with a research team from the University of Wisconsin led by materials science and engineering professor Chang-Beom Eom, and research associates Chung Wun Bark, Jae-Wan Park, and Chad Folkman.
A sharp conducting probe of an atomic force microscope was used to create nano-sized wires and transistors at the interface of a crystal of strontium anate and a 1.2nm thick lanthanum aluminate layer. The devices can later be erased, allowing the interface to be reused. The SketchSET comprises an island structure that could hold zero, one or two electrons. This numbers causes specific conductive traits. Wires protruding from the transistor deliver more electrons over the island.
The single-electron device is sensitive to an electric charge and exhibits ferroelectricity, due to which the transistor serves as a solid-state memory. The ferroelectric state can also monitor the number of electrons on the island when there is no external power source. A computer memory that was based on this characteristic could retain data when the processor was shut down. It could also prove susceptible to nano-scale pressure changes like a nanoscale charge or force sensor.
That's badass, except for the "retaining data" bit, which data thieves would love.
Honestly, we live in an amazing time. DNA splicing, nano-tech, quantum physics... It's awesome.
and how much for the transfer would cost?
imagine if it didnt destroy the original and just clone and transfer...OBAMA will put in 13triillion and clone that and send it over to china, NFD = zero
Cloning technology would completely screw up every economy in the world.
Additionally, money wouldn't just "appear". The new money would be formed from atoms, which will have had to come from someplace else. So not only would you have to develop cloning, but also find a way to transmute matter.
