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 ...

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.

Early in the development of quantum mechanics, the uncertainty principle made its appearance, along with the inevitable noise that accompanies a measurement. Over the years, most physicists came ...

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