There it is. Your DC-to-daylight receiver.
If it emits RF, it’ll hear it.
Frequency-hopping etc. be damned, you’re audible.
Even more on the story.

Plug a computer into a quantum receiver that is connected to an array of space antennas in orbit around the planet and on the moon and AI could look for anything you want on any frequency / frequencies you want: supernova, planetary nebula, galactic lenses, black holes, exoplanets, moons, transits, gas clouds, brown dwarfs, magnetic fields, galaxies, clusters, voids, star types, asteroids, comets….

There would be more data coming in than the SKA. An array of quantum computers and next level storage might be able to deal with that?
What else could be looked for…
A set of data, things like black hole collisions, neutron star collisions, asteroid threats to Earth, and perhaps more importantly things that are not in the database of data, so unusual things like black holes disappearing, UFO’s, strange circles appearing in deep space, data thats’ not in the database set.
Ambient surface lighting is really impacting on world astronomy so a future open network of astronomy satellites with antennas pointing to deep space could be a way around that problem.
15 Things Everyone Should Know About Quantum Computing
Big Atoms Make Small, Super-Sensitive Quantum Receivers
Classical physics describes how big things behave and interact in our physical world. Throw a ball into the air, and you know it will go up and come down in a predictable path every time. In the quantum realm, if you could throw something up, it might come down, or it might not, or it might come down in another city. That is because quantum mechanics governs the ultra-small world of atoms, electrons, and photons. It is an invisible world where particles mysteriously disappear then reappear, where particles exert an influence on other distant and unconnected particles, and where particles can assume many quantum values at the same time. To add to the strangeness, some scientists believe that quantum particles can time travel. In contrast, others believe particles behave strangely because they move in and out of alternate universes.

In 2016, IBM added a small quantum computer to the cloud. Anyone with an internet connection can design and run their own quantum circuits on this computer. A quantum circuit is a sequence of basic steps that perform a quantum calculation.Not only is IBM’s quantum computer free to use, but this quantum computer has a simple graphical interface. It is a small, not very powerful machine – much like the first home computers – but hobbyists can start playing. The shift has begun.

Could Rydberg atoms detect gravity waves?
Quark receivers would be detect lots of gravitational waves.
Plank receiver?
A Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number, n. The higher the value of n, the farther the electron is from the nucleus, on average. Rydberg atoms have a number of peculiar properties including an exaggerated response to electric and magnetic fields, long decay periods and electron wavefunctions that approximate, under some conditions, classical orbits of electrons about the nuclei. The core electrons shield the outer electron from the electric field of the nucleus such that, from a distance, the electric potential looks identical to that experienced by the electron in a hydrogen atom.

Get a sweep of everything at once, lots of data at once to deal with.
If I get the gist of it, its a spectrum analyser based on a certain type of atom, its that atom that acts as a wide band receiver.
Ok I would like to have a quantum receiver built into my next new telescope with the Vanta black tubes and other goodies.
Ill have a quantum receiver or several quantum receivers built into the next smartphone Samsung galaxy S25?, along with a quantum computer chip.

How does this work? Wikipedia says:
A Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number, n. The higher the value of n, the farther the electron is from the nucleus, on average. Rydberg atoms have a number of peculiar properties including an exaggerated response to electric and magnetic fields, long decay periods and electron wavefunctions that approximate, under some conditions, classical orbits of electrons about the nuclei.
The arrival of tunable dye lasers in the 1970s allowed a much greater level of control over populations of excited atoms. In optical excitation, the incident photon is absorbed by the target atom, absolutely specifying the final state energy. The problem of producing single state, mono-energetic populations of Rydberg atoms thus becomes the somewhat simpler problem of precisely controlling the frequency of the laser output.
The large separation between the electron and ion-core in a Rydberg atom makes possible an extremely large electric dipole moment, d. There is an energy associated with the presence of an electric dipole in an electric field, F, known in atomic physics as a Stark shift.
I still don’t follow how it works. A Rydberg atom is unstable, both ways, it rapidly decays to lower energy states, and the slightest perturbation pushes it into ionisation.

More on the storyScientists create quantum sensor that covers entire radio frequency spectrum
https://www.army.mil/article/212935
> Such wide spectral coverage by a single antenna is impossible with a traditional receiver system
Not necessarily. A sufficiently accurate spiral antenna has a very wide range of frequencies.
> While Rydberg atoms are known to be broadly sensitive, a quantitative description of the sensitivity over the entire operational range has never been done
Good point.
> To assess potential applications, Army scientists conducted an analysis of the Rydberg sensor’s sensitivity to oscillating electric fields over an enormous range of frequencies—from 0 to 1012 Hertz. The results show that the Rydberg sensor can reliably detect signals over the entire spectrum and compare favorably with other established electric field sensor technologies, such as electro-optic crystals and dipole antenna-coupled passive electronics.
Dipole! Could that be enough on its own with appropriate electronics?
> the Rydberg atoms’ exquisite sensitivity to electric fields
Hmm, possible.
> these atoms naturally operate over a very wide band of frequencies (from kilohertz (10^3 Hz) to terahertz (10^12 Hz)
Heck, that’s wide. I’m glad that said kilohertz instead of zero. There’s a lot of difference.
> For the ARL team, their atoms are held in a simple glass cell at room temperature, and they use two colours of laser light to simultaneously excite the Rydberg states and probe their reaction to the external electric fields
OK. That’s pretty standard.But I think it limits detection to scanning. The second laser scans through the frequency band.

3-D trapping of Rydberg atoms in holographic optical bottle beam traps
Physicists show feasibility of building a trapped Rydberg ion quantum computer
To carry out their research, the scientists used a device called a magneto-optical trap to capture a cluster of Rubidium (Rb) atoms. They reduced the temperature of the atoms to approximately 120 microKelvin—fractions of a degree above absolute zero and ran a nanofiber through the atom cloud.
Then, the scientists excited the Rb atoms to a more energetic Rydberg state, using a 482 nm beam of light travelling through the nanofiber.
What’s ‘n’ for 482 nm and rubidium?
