Quantum light breakthrough could transform technology

Scientists achieved a major breakthrough by using exotic quantum materials called topological insulators to generate terahertz light frequencies that were previously impossible to create. By integrating these materials with specialized nanostructures, researchers successfully produced both even and odd harmonic frequencies between 6.4-9.7 THz for the first time. This advancement could lead to compact terahertz devices for high-speed communications, medical imaging, and quantum computing applications.
