With just a single atom, light can be switched between two fiber optic cables. Such a switch enables quantum phenomena to be used for information and communication technology. With just a single ...

With just a single atom, light can be switched between two fibre optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and ...

Understanding atom-light interaction in multi-level settings is an extremely difficult problem, and up to now it has eluded ...

But quantum physics comes to the fore in ultracold, dense atom clouds. “The way they interact with light or scatter light is different,” says physicist Amita Deb of the University of Otago in ...

How light is detected affects the atom that emits it An experiment suggests it might be possible to control atoms entangled with the light they emit by manipulating detection Date: May 12, 2016 ...

Another laser is then used to transfer the atom to another excited state, from which it decays back to the ground state – allowing the whole processed to be repeated. The light emitted by one-atom ...

But using light to control the state of an atom could provide the basis for new applications—molecules that emit different colors, for example, to distinguish them in biological processes.

This light-driven oxidation creates a cation radical ... electron-transfer rate appears to be just right to enable a clean atom swap. Park says he and his team are working on developing more ...

A quantum computer has used a single atom to model the complex dynamics of organic molecules interacting with light ...
