Teleportation: Science Fiction or Science Fact. Quantum Computing is Advancing the Notion.  
Quantum photon entanglement has been proven to enable near-perfect secrecy of data transmission.  In a sense, quantum entanglement utilizes teleportation, albeit very simplistic compared to what we find in the likes of Star Trek episodes. 
Research into quantum computing has led to what we now know as quantum teleportation.

“By taking previously-entangled particles and placing them in different locations, we can use traditional communication methods to send the states of one particle to the entangled partner no matter how far apart they might be.”  Even if it is Alpha Centauri.
