Harvard scientists have created the world’s smallest radio receiver out of diamond imperfections called nitrogen-vacancy (NV) centres. The NV centers are capable of emitting single photons or detect very weak magnetic fields. When the NV centers receive radio waves it will convert them and emit the audio signal as red light. A common photodiode will convert ..
