I honestly have no idea what quantum physics is (sciencewise). I love all these discussions, but I'll have to sit this one out :(
Pretty sure it has to do with time and movement though.

This doesn't have muuuch to do with quantum physics, but it's got some principals that are undeniably intertwined.
Recently, I learned of a theory called the "Transcendence hypothesis". It's an answer to Ferme's paradox, which states that if there is so much in the universe and so much potential for intelligent life, why don't we see signs of it everywhere?
The hypothesis states that instead of expanding and venturing out into the universe, technology is going to enable the ability to travel inward. The goal of technology is the make it smaller and more complex, which in turn makes it more dense. The amount of energy per gram that goes through a microchip is greater than that of the surface of the sun. The energy density of current days chips is already ridiculous, and they are only going to get smaller and better!
Now, the densest thing in our universe is a black hole. There is an amazing amount of energy per gram and mass within such a small point. The Transcendence hypothesis states that the natural advancement of technology will create a black hole (the ultimate computer) and that this will open up a new dimension from a single point, which is a viable explanation for the Big Bang theory.
The gist of the hypothesis is this: It seems that technology mimics the natural design of the universe and everything within it. Perhaps it's so natural because that is how our very own universe was created. Perhaps the goal of intelligent life (which is essentially just the universe itself, since we are all made of consciousness) is to transcend. Many people talk about how eventually our universe will be dark and everything will be so spread out that there will be no chance for life to survive. After every star burns out and everything floats farther and farther away, there will basically be nothing left. Maybe intelligent life (which as I mentioned above is just a way for the universe to act and discover) is supposed to open a new universe to continue the "legacy".
Sorry if some things don't make sense, It's hard to explain something like this with just word :p

ibm labs have quantum qubits and had for a while
but the best part about quantum physics is entanglement - first photon teleportation was done, i believe, more than a decade ago, but over distance of 1 meter - about 3 feet… but more recently they quantum teleported over 16km (10 miles) distance
http://phys.org/news193551675.html
edit: apparently in recent days 60km teleportation was announced

Lol. Teleportation is real.. I'm liek, soo sm4r7, 17'5 n07 3v3n funny.

That's not exactly teleportation.. That's just stuff moving really fast. I'd say the only teleportation ever truly announced was the Quantum entanglement of two twin particles at a distance. One actually just magically appears where the other one is no matter how far apart. If you find an explanation, you get a noble prize lol.

And that brings us onto Bell's theorem. The local or non-local universe.
That's not what happens. The quantum state of one particle of the entangled pair is measured. Then we therefore know the other quantum state of the other particle in the entangled pair instantly. It is pretty useless to us right now (for teleportation) but maybe in the future we might have a use for it.

Your talking about an entirely different topic of quantum mechanics on particles.
Two particles at an arbitrary distance when entangled and measured, an action done to one will happen to the other. That's totally different from what I was talking about. But the Bell's theorem does apply. I was trying to explain the Bob-Alice thing but I guess I messed up. You guys can Google it though and see what I mean.

Still not seeing what you mean, when you do the 'Alice Bob thing'. You do not transport any energy or matter. No physical particles will have moved between Alice and Bob which was implied by your post.

In regard to the "Transcendence Hypothesis": a theory acts to quantify what has yet to be quantifiable. Man seeks to gather understanding, and hence applies theory to comprehend to what are innately incomprehensible concepts. The Universe, with its subsequent laws and many intricacies, presents a canvas: blank, unfilled, and undefined. The human condition - that is to say, the perspective of the individual - adds paint to this metaphorical canvas, providing what some may call "art". The hypothetical goal put forth by the "Transcendence Hypothesis" acts to put meaning behind the existence of our Universe when in fact, man contrived and subsequently defined the term existence; hence, "existence" - that is, the concept of existence - purely represents a man-made ideal as opposed to a hidden agenda inscribed within the fabric of our known and unknown Universe- and any other Universe for that matter. Rather than question the meaning of existence, ponder the theme of the existence you created. Before testing a hypotheses, make sure you are asking the right question.
In the interest of topicality: what is your favorite flavor of quark? Personally I prefer top for it is rare, positive, and large - yet sadly, all too fleeting.

What about Quantum Electrodynamics? It's the first theory that has agreement between Quantum Mechanics and Special Relativity. Paul Dirac and Hans Bethe were the predecessors to Quantum Physics in all, from what I've read.
