2D material in three dimensions

The carbon material graphene has no well-defined thickness; it merely consists of one single layer of atoms. It is therefore often referred to as a "two-dimensional material." Trying to make a three-dimensional structure ...

The perfect trap: A new way to control the polarization of light

For quantum communication or optical computing it is important to measure and to influence in which direction a light wave is oscillating. It is now for the first time possible to manipulate this polarization of a continuous ...

Building a silicon quantum computer chip atom by atom

A University of Melbourne-led team has perfected a technique for embedding single atoms in a silicon wafer one-by-one. Their technology offers the potential to make quantum computers using the same methods that have given ...
