At the Vienna University of Technology (TU Wien), two photons were made to interact strongly using an ultra-thin glass fiber. This technique is an important new tool for quantum technology.
With just a single atom, light can be switched between two fiber optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology.
A light wave oscillates perpendicular to its propagation direction – that is what students learn in school. However, scientists of the Vienna University of Technology (TU Vienna) now perform atom-physics experiments with light oscillating in the longitudinal direction.
Glass fiber cables are indispensable for the internet – now they can also be used as a quantum physics lab.
Light is intangible and, in addition, it travels at great velocity. Nevertheless, it can be confined to a very small space by controlably inserting light into a microscopic container surrounded by reflective walls.
