If that is what they wanted to say they did a very bad job. And spooky action at a distance is a term related to quantum entanglement, which has probably nothing to do with the phenomenon they tried to describe here.

You're right; this is nothing to do with spooky action at a distance.
But sympathetic response, or resonance, is how this device would work---just like a radio. Axions couple to electromagnetism; by listening in on different frequencies we can see if there is any "cosmic signal being broadcast" (meaning: axions suffusing the galaxy); the frequency of the signal corresponds to the mass of the axion.
In that sense, the search for resonances is a classic approach in particle physics; various particles were discovered by finding increased signals at particular collision energies. What's different here is that it isn't a resonance in a collision cross-section but an axion --> electromagnetism conversion.
Any chance this could lead to a resonance cascade? I saw some documentary where that happened at a remote corporate facility in the desert somewhere...Dark Table maybe. I was surprised to see such heavy use of a crowbar at a place doing advanced physics. ;-)
