I saw from Integral Options, that scientists are reporting success in quantum teleportation.

That's pretty cool!

At any rate, the Wikipedia has a couple of good articles. 

One on quantum teleportation.

One on why it works, quantum entanglement.

From what I understand, in no way is this the normal understanding of teleportation, but have to do with the weirdness of quantum measurement, and exploiting the properties thereof. 

Two interacting pairs that have been entangled, if you measure one pair, you immediately know the state of the other pair.  From a wikipedia article:

Einstein coined the term "spooky action at a distance" or "SPAD" to describe these situations, which exhibit quantum entanglement. Relativistic quantum field theory requires interactions to propagate at less than the speed of light, so quantum entanglement cannot be used for faster-than-light-speed propagation of matter, energy, or information. However, it must be understood that a change to one entangled particle does indeed affect the other instantaneously, but this is only known after the experiment is performed and notes are compared, therefore there is no way to actually send information faster than the speed of light.
