Star Trek’s Vision Becomes Reality

Physicists from University of Jena for the First Time Demonstrate Teleportation of Classic Object

„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 centre, this command was enough to take him back to the control centre instantly – travelling through the infinity of outer space without any loss of time.

But is all of this 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.

“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 Juniorprofessor 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 now for the first demonstrated in an experiment that the concept of teleportation does not only persist in the world of quantum particles, but also in our classical world. Szameit and his colleagues report about these achievements in the scientific journal “Laser & Photonics Reviews” (DOI: 10.1002/lpor.201500252).

They used a special form of laser beams in the experiment. “As can be done with the physical states of elementary particles, the properties of light beams can also be entangled,” explains Dr Marco Ornigotti, a member of Prof. Szameit’s team. For physicists, “entanglement” means a sort of codification. “You link the information you would like to transmit to a particular property of the light,” clarifies Ornigotti who led the experiments for the study that was now presented.

In their particular case, the physicists have encoded some information in a particular polarisation direction of the laser light and have transmitted this information to the shape of the laser beam using teleportation. “With this form of teleportation, we can, however, not bridge any given distance,” admits Szameit. “On the contrary, classic teleportation only works locally.” But just like it did at the starship USS Enterprise or in quantum teleportation, the information is transmitted fully and instantly, without any loss of time. And this makes this kind of information transmission a highly interesting option in telecommunication for instance, underlines Szameit.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
