Dirty diamonds will help create a quantum internet
How to build a quantum internet
The crystal lattice of a diamond is made up of carbon atoms, each of which is bonded to four neighboring. Researchers found that if a replace some atoms with silicon, then new a type of diamond can emit photons at a well-defined and stable frequency. It is possible thanks to high coherence systems and synchronicity of electron spins.
For now this is does not bring us much closer to creating a quantum internet, So as under normal conditions the light emission is not strong enough. For to achieve the desired effect, silicon-vacancy diamonds must be under pressure, which about at 10 o’clock thous. exceeds atmospheric. Scientists consider this to be the main obstacle to the application. «dirty» diamonds in technologies the future. but created system can work forever, and it is possible that already soon will be found a solution to the existing problem.
