Nano Diamond New Structure is Expected to Achieve Quantum Computation Process in Advance

Researchers from the United States have successfully developed a new structure of nano diamond, planning to work with the government and enterprises to explore self-assembly system of new nano diamond and produce new components for quantum computers.

The new structure contains a nitrogen atom and an atomic vacancy, which can be applied to quantum computing, single photon sensor and non-toxic fluorescent biomarkers under the condition of room temperature.

Diamond is composed of a myriad of diamond crystals, and usually each crystal contains five carbon atoms. Scientists at University of North Carolina make every crystal contain only two carbon atoms through the latest technology, and the remaining three locations are atomic vacancy, a carbon-13 atom (a stable isotope of carbon element) and a nitrogen atom.

This new structure is called NV center, and each NV-doped nano diamond contains only a crystal with NV center, and the remaining crystals are ordinary carbon diamond crystals. In this way, it can make NV center switch between two kinds of transition states through current or laser control, and new nano diamond can become the basic qubit of quantum computer. Because quantum computing requires each qubit with more states in addition to ordinary binary 0 and 1.

Researchers will cooperate with the government and enterprises to jointly explore self-assembly system of new nano diamond, and produce this highly innovative components for quantum computers.
