“Beam me up, Scotty”—even if Captain Kirk supposedly never said this exact phrase, it remains a popular catch-phrase to this day. Whenever the chief commander of the television series’ starship USS Enterprise (NCC-1701) wanted to go back to his control center, this command was enough to take him there instantly—travelling through the infinity of outer space without any loss of time.
But is all of this just science fiction that was thought up in the 1960s? Not quite: Physicists are actually capable of beaming—or “teleporting” as it is called in technical language—if not actual solid particles, at least their properties.
Transmission of information without loss of time
“Many of the ideas from Star Trek that back then appeared to be revolutionary have become reality,” explains Prof. Dr. Alexander Szameit from the University of Jena (Germany). “Doors that open automatically, video telephony or flip phones—all things we have first seen on the starship USS Enterprise,” exemplifies the junior professor of Diamond-/Carbon-Based Optical Systems. So why not also teleporting?
“Elementary particles, such as electrons and light particles, exist per se in a spatially delocalized state,” says Szameit. For these particles, it is with a certain probability, thus, possible to be in different places at the same time. “Within such a system spread across multiple locations, it is possible to transmit information from one location to another without any loss of time.” This process is called quantum teleportation and has been known for several years.
The team of scientists, lead by science-fiction fan Szameit, has demonstrated for the first time in an experiment that the concept of teleportation not only persist in the world of quantum particles, but also in our classical world. Szameit and his colleagues report these achievements in the scientific journal Laser & Photonics Reviews (DOI: 10.1002/lpor.201500252).
