Slide image: The slide shows two nano structures against a background of parallel, receding, converging lines.
The top structure is a molecule, which is currently the world's most advanced quantum computer -- a 7-qubit quantum that IBM researchers used to conduct the first demonstration of Shor's quantum factoring algorithm. 

The bottom structure is a semiconducting metal junction formed from two carbon nanotubes.
