DailyTech - Nanotech Produces Bizarre "Flat" Atom, Hailed as Quantum Computing Breakthrough

"Imagine a tiny arsenic atom embedded in a tiny strip of silicon atoms. An electric current is applied. Something strange arises on the surface -- an exotic molecule. On one end is the spherical submerged arsenic atom; on the other end is an "artificial" flat atom, seemingly 2D, created as an artifact. The pair form an exotic molecule, which has a shared electron, which can be manipulated to be at either end, or in an intermediate quantum state"
