Pretty big win for RF. Peak sensitivity -145 dBm/Hz. Little bit of a stretch to say entire RF spectrum, but 0 -> 20 GHz is still really cool.
"In March 2020, the laboratory announced that its scientists analysed the Rydberg sensor's sensitivity to oscillating electric fields over an enormous range of frequencies—from 0 to 10^12 Hertz"
The antenna in mobile phones perform well across a wide range of frequencies due to being fractals!
A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously.
Is this inaccurate?
The associated electronics are obviously necessary too.
