Researchers at the University of Warsaw have unveiled a breakthrough method for detecting and precisely calibrating terahertz frequency combs using a quantum antenna made from Rydberg atoms. By combining atomic electrometry with a powerful terahertz-to-light conversion technique, they achieved the first measurement of a single terahertz comb tooth—something previously impossible due to the limits of electronics and optical tools.

“Until recently, the terahertz range was considered a blank area in the electromagnetic spectrum… positioned between microwaves (used, for example, in Wi-Fi) and infrared … it holds immense potential for applications that include inspecting packages without harmful X-rays, superspeed 6G communication, and spectroscopy and imaging of organic compounds…”

    This comment is perfect. Science can only now serve the useless musk-o-vite elite. Otherwise, it can’t be funded.
