Story summary

Researchers at the University of Warsaw have developed the first all-optical radio receiver that detects radio waves without metal antennas using laser light and Rydberg atoms.
The device offers self-calibration and sensitivity by measuring through shifts in infrared light from rubidium atoms excited to Rydberg states.
The technology has potential applications in telecommunications and scientific instrumentation, attracting interest from military and space agencies because findings were published in Nature Communications.
