In a tiny quantum prison,electrons behave quite differently as compared to their counterparts in free space. They can only occupy discrete energy levels, much like the electrons in an atom - for this reason, and such electron prisons are often called "artificial atoms". Artificial atoms may also feature properties beyond those of conventional ones,with the potential for many applications for example in quantum computing. Such additional properties acquire now been shown for artificial atoms in the carbon fabric graphene. The results acquire been published in the journal Nano Letters, the project was a collaboration of scientists from TU Wien (Vienna, or Austria),RWTH Aachen (Germany) and the University of Manchester (GB).
