However, an atom releases a light particle in all possible instructions– recapturing this photon is therefore rather hard.A research team from TU Wien in Vienna (Austria) has actually now been able to show theoretically that utilizing a special lens, a single photon emitted by one atom can be ensured to be reabsorbed by a 2nd atom.” In this method, it is possible to guarantee that all rays originating from one atom reach the lenss edge on a curved course, are subsequently reflected, and then get here at the target atom on another curved path,” describes Oliver Diekmann. “We were able to reveal that the coupling in between the atom and these different oscillating modes can be adapted in such a method that the photon is transferred from one atom to the other one nearly certainly– rather various from what would be the case in complimentary space. The game begins over: the two atoms swap roles and the photon is returned from the receiver atom to the initial sender atom– and so on.Optimal Control for Quantum TechnologiesSo far, the effect has been demonstrated in theory, but practical tests are possible with todays innovation. “In practice, the performance could be increased even further by utilizing not simply two atoms, however two groups of atoms,” says Stefan Rotter.

The video game begins over: the two atoms swap functions and the photon is returned from the receiver atom to the original sender atom– and so on.Optimal Control for Quantum TechnologiesSo far, the impact has actually been shown theoretically, but useful tests are possible with todays technology.
