Electronic espionage era concludes with unbreakable photon chip

An international research team led by the University of Technology Sydney in Australia successfully developed a mechanical method to control quantum light sources and modulate their energy at room temperature. The technique relies on hexagonal boron nitride material, which contains atomic defects that enable the emission of single photons with tunable properties through precise mechanical rotation of its layers. This control allows for significant changes in the color and energy of the emitted photons—over 30 nanometers—under normal temperature conditions. Such advancements enhance applications in quantum computing, secure communication networks, and ultra-precise sensors, with future challenges focusing on developing automated and systematic systems to transfer the technology from laboratory experiments to industrial production lines.
