Russian and Japanese physicists created a superconducting chip, which can serve as an artificial atom.
      
      The work of the physicists allows human beings to create energy levels, which differ from natural ones, present in atoms, listed in the Mendeleev periodic table.
      
      Artificial atoms can be made on a chip. They are much larger than natural ones, thus have stronger interactions with electromagnetic radiation. Such “atoms” can be elements of quantum generators, for instance.
      
      A prototype of an artificial atom looks like a metal film on an ordinary silicon chip. The object has several components: waveguide lines for taking microwave radiation in an out, a resonator, and an islet superconducting structure with nanometer tunneling transitions. This islet is an artificial atom.
      
      Among possible applications of the discovery there is a possibility of creating a laser with non-threshold regime of laser generation.
