A company called Infleqtion already has an RF sensing product that uses Rydberg atoms.

Is it really a product already? There are a number of renders but the 'products' link does not work for me.

Not sure if it's being "actively" used in real-world deployments yet, but it does exist.

That page uses the older versions of "SWaP-C2 Optimized[1]" meme, I would guess it might have not been updated in 3-5 years.

1: Stands for "Size, Weight, and Power [and] Cost [and] Cooling Optimized", defense industry equivalent of self awarded gold medal stickers on product packaging, apparently
