Rydberg atom quantum sensing enables high-accuracy Ku-band antenna gain measurement
Researchers used Rydberg atom quantum sensing to measure the gain of a Ku-band microwave antenna with exceptional precision. This new technique offers a more reliable, atom-based calibration standard that could replace traditional antenna measurement methods. The approach matters for improving microwave metrology in radar, communications, and applied physics.
