This looks interesting.
Will it fit in a backpack ?
Wonder if it could help with things like astronomy or planet to planet communication. If the receiver is quite good, that could help a great deal.

Imagine being able to text someone directly, antenna to antenna, over distances of hundreds of KM
The bandwidth wouldn't be great, but it would be nice to send a simple text SMS to someone without any relays in between
That would be reinventing James Harris Rogers WW-I system.
T.E.Bearden claimed that this system has been rediscovered and "lost" several times.
that's an interesting footnote...
Check out the list of Curl-Free Magnetic Vector Potential patents by Raymond C. Gelinas assigned to Honeywell.
The performance is quite a bit worse than conventional semiconductor based RF spectrum analyzers which can be carried around. Maybe they have some ideas how to improve it in the future. Currently it is clearly just a proof of concept that shows that Rydberg atoms can be made sensitive to broadband RF at all.
