This is what I predicted a couple years ago!  A means to observe quantum particles without destroying them!

This will finally make it possible to utilize quantum entanglement for what amounts to Star Trek's 'subspace communications', at least thousands of times faster than light. The old methods of observation using intense radiation were, as I likened them to, viewing a glass vase with a battering ram. With subtler methods such as this, it is much more likely the entangled atoms can be viewed without destroying the link, thus many motions can be induced and viewed in the same pair or group of entangled atoms (or even sizeable compounds, which would be much easier to incorporate into a communications device.) The induced motions, while not directly a 'signal' would be the basis for a code system. Let us say simply, changing the vibrations of the particles a certain way would constitute a '0' and another way to represent '1'. And there we have binary code, and instantaneous abstract transmission of information without actually breaking any fundamental physics laws.

Hmm, warp speed theoretically feasible now, subspace communications... all in the 21st century as Gene Roddenberry predicted!  HE AS A PROPHET FROM THE FUTURE!!!!  D:

Go team science? To be fair though, graphene transistors are the next step forward, as they will be a hypermassive improvement over silicone transistors, while easily within reach of out current technology. Remember we need to learn to walk before we cun run, but still, Quantum computing is the future! (Currently)

Edit: Btw 1 terabyte optical disks are in developement

This isn't just about quantum computing.  Making even simple binary code-based utilization of quantum entanglement will make interstellar communication possible.

The last series of experiments I'd heard about attempting to set a minimum (MINIMUM speed, mind you) for the entanglement effect came up with 10,000 times the speed of light.

With that minimum speed, a communication sent to the Alpha-Beta-Proxima Centauri system via 'entanglement resonance interpretation' (my term for the method) would only take around 4 hours versus a bit over 4 years at light speed.

It'll make probes easier to control within the solar system as well, with instructions to and data flow from the probes essentially instantaneous.

Indeed, but it is very limited channel-wise (cant entangle more than 2 atoms at once and you have to make them entangled, so you cant CREATE communication channels long distances away, you have to manually separate the 2 atoms., and thus would not be practical for any mass communication. This would mean that while good for official communications that were pre-created, it would be very impractical for mass media.
(also on a side note quantum entanglement is different from the quantum computing generally mentioned which work on the positive/negative charges of atoms)
but it would, as you said, excel for stuff like deep space probes.

Aaaactually, you can entangle huge compunds now.  .  From wikipedia:  "Quantum entanglement occurs when particles such as photons, electrons, molecules as large as buckyballs,[1][2] and even small diamonds[3][4] interact physically and then become separated;"

The speed experiments were done by manually separating entangled atoms and then seeing how quickly the transmission occurred.  So far, they can separate them by over 1,000 miles using relatively simple means.  It was always observing the effect that was the problem.  Observing it destroyed it, for the same reason that the crux of this development is nso important.  Observations can now be made without destroying the particles.  And since you can entagnle large molecules, it means the effect is much more obserrvable as more easily contained. 

So you have one pair of particles be '1' and other be '0'.  Then you just  'ping' them in whatever binary information you wish to send.  The universe doesn't know that the seemingly random jitters of the entagled atoms/molecules mean something to us.  It's an abstract code, after all.  So we trick the univese into sending information faster than light without breaking the fundamental laws.

That's new for me, but yes, you are correct.

Doesn't Quantum entanglement act like this: there are 2 particles, they do not have a defined state, they can be (let's take a coin for example) either heads or tails, we have no way of knowing what the state is untill we observe it, BUT since they are entangled if one coin is heads, then the other always will be tails.
Ok, so let's say that Alice has particle A here on earth, and Cooper is light years away in deep space with particle B. They want to use their entangled pair to send a signal. Well, if Alice measures A, she can't control which outcome she gets, so she can't control which outcome Cooper gets. That makes it hard to send any information, no?. Or am I confusing quantum teleportation communication with quantum teleportation communication?
