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.

#12Does anyone have insight into why this is published in the open literature, if it is such a militarily-exploitable advance?

Right. If it went into the terahertz range, it would help open up that area. 5G cell phones go higher than 20GHz than that.

#14Miniaturization and ruggedization for practical applications will require a lot of work. Not only are the atoms contained in a heated tube, but, unlike atomic clocks, sophisticated tunable laser technology must also be employed. So only very high value missions, like large satellites or ground installations are practicable.

#18When Voyager stumbled upon a industrial-age civilization Kim immediately notified Janeway that he's detecting "Old style" FM broadcasts. I recall thinking "why would a 24th century subspace-communicator equipped star ship even monitor those?"
I got my answer, quantum receivers, they monitor everything.

Even so, this is pretty impressive, not all that long ago this device would be SF and people would doubt it would ever exist.
