Although experts around the world are also addressing these problems (one tenth of a nanometer), few laboratories can make progress on both.
Researchers are simultaneously mastering the progress of single-photon and molecular research. The Moscow Institute of Physics and Technology (MIPT) is currently researching an advanced diamond technology that emits single-photons (used to break cybersecurity) and detects single molecules (for early detection). Pathogen) of graphene. Although experts around the world are also addressing these problems (one tenth of a nanometer), few laboratories can make progress on both.
MIPT Nano-Optics and Plasma Laboratory Researcher Dmitry Fedyanin teamed up with Mario Agio, a researcher at the University of Siegen in Germany, to solve the most problematic problem in the indestructible quantum code. By using diamonds as a high-speed emitter of ohmic-encoded photons, researchers have opened the door to high-density (ie, 100MHz high-speed) quantum key communication. 20160824 MIPT NT01P1 Laser photonic version design - spaser, and graphene layer (cellular lattice above the electrolytic layer).

“Our research focuses on the design and development of infrared single-photon sources that provide high-intensity single-photon rays under electric pumps, as well as energy-efficient features that operate at room temperature and temperature,†says Fedyanin.
Currently, the use of indestructible key single photon sources (such as quantum dots), usually operating at very low rates - only a few photons per second, makes the light extremely dim. They also usually need to be extremely cooled. MIPT's diamond-based technology works at room temperature and generates 100 million indestructible quantum keys at about 392 degrees Fahrenheit, making the single photon source very bright and low cost. If researchers can confirm the reliability of this research, then all quantum cryptography companies may have to be forced to take this technology license.
However, it seems that the target has not yet been achieved. There are still several engineering obstacles to be overcome, but the researchers are very confident that they can overcome these obstacles after a few years of research and development. 20160824 MIPT NT01P2 Single-molecule detector in the early prototype stage, when metal was used instead of graphene (Source: MIPT)

“Our next step is to overcome the technical problems of diamond doping and color center implantation, which makes it impossible to observe true ultra-high brightness single photon emission from electrically driven drill diodes. We are also working to make single photon emission diodes more compact. We will reduce the size of the component to a few hundred nanometers in order to design a true nanoscale quantum optical circuit for a linear optical quantum computer and further realize a single quantum photon computer. At the same time, we want to use the nano-optical effect and use micro Human advantage, improve the efficiency of the component and quantum yield, achieving nearly 100% efficiency," Fedyanin said.
