"...marketing fluff around a Rydberg spectrum analyzer..."

How about the price point?

The paper speaks of DC to 1 THz. Any good spectrum analyzer I know of for anything close to that range, is going to have a lot of zeros in the price tag that puts it out of the budget of just about everyone.

Even covering all of 5G or newer automotive RADAR at 77 GHz is out of most budgets.

Marketing is not always about retail sales. Its a necessary evil ever since the Golden Fleece awards were used to neuter basic research.

Grant proposals are more about a marketing push than science these days. The article and associated paper are really just fluff so that they can keep doing research in spite of incompetent oversight.
