Physicists Discover How To Teleport Energy

MikeChino writes "A physicist at Tohoku University in Japan has figured out how to teleport energy from one point in the universe to another. The technique is based upon prior research that shows it's possible to teleport information from one location to another, and involves making a measurement on each [of] an entangled pair of particles. The measurement on the first particle injects quantum energy into the system, and then by carefully choosing the measurement to do so on the second particle, it is possible to extract the original energy. Heady stuff, but essentially it means that you can inject energy at one point in the universe and extract it from somewhere else without changing the energy of the system as a whole."

Quantum "Teleportation" isn't teleportation at all

[DigitalEntropy]

There is nothing transmitted between "entangled" particles, nor are any relevant bits of information passed between them in any method that comes close to the definition of "teleportation", or even "transportation". The quantum mechanics behind "entagled" particles should be described like this:

1.) You have 2 Rubick's Cubes.
2.) You "entagle" them by making the faces of each Cube exactly identical to the other.
3.) You separate them physically into different geological locations.
4.) You "measure" Cube A by turning one of its sides.
5.) You call a handler at Cube B using a "common channel" (phone).
6.) Cube B is "measured" by having its identical face turned exactly replicating Step 4, per the instructions received by step 5.
7.) Repeat steps 4 through 6 until your heart is content.
8.) Bring the Cubes together, and marvel that their faces are still identical to each other.

I think the principle problem with "quantum teleportation" is that any measurement on one Cube which is not duplicated exactly on the other, breaks the entanglement of the particles. They are only "entangled" in the sense that their states have been synchronized. There may be avenues of recovering the synchronization using permutations of "measurements", but then I haven't read much about what occurs during an error or fault in measurement, so this is all just my best guess.
