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.
