American researchers have successfully developed a new structure for nanodiamonds, and plan to work with governments and companies to explore new nanodiamond self-assembly systems to produce this innovative and low-cost new component for quantum computers. 
Diamond consists of a myriad of diamond crystals, usually containing five carbon atoms per crystal. Scientists at North Carolina State University use the latest technology to make crystals contain only two carbon atoms. The remaining three positions are atomic vacancies, one carbon-13 atom (a stable isotope of carbon), and a nitrogen atom.
This new structure is called NV center, and each NV-doped nanodiamond contains only one crystal with NV center, and the rest of the crystals are ordinary carbon diamond crystals. In this way, the NV center can be switched between two transition states by current or laser control, and the new nano-diamond can be used as the basic qubit of the quantum computer. Because quantum computing requires each qubit to have more states than the normal binary 0 and 1.
The researchers will next work with governments and companies to explore new nanodiamond self-assembly systems to produce this innovative and low-cost new component for quantum computers.
