It should be possible to set up an experiment with entangled photons and use your eyes as the detector. We could literally see quantum mechanical behavior with our own eyes! Pardon my crudeness but how fucking cool is that!
I'm not sure what would you expect to see anyway. A photon in two places at once? That's not how it works. The wave function tells you where a particle can be detected, and that can be in several places, but in the end it is only actually detected in only one of those places.
That occurred to me as well as I read that article. It certainly raises some interesting questions about potential observations and wavefunction collapse.
Anyway there was an article on Ars recently about directly observing entanglement, so it's kind of already been done.
Probably wouldn't tell us much about the characteristics of the light either.
They used a microscope to look at the flashes of fluorescent light created after the alpha particle scatters from the foil.
(We could repeat this experiment in upper-level physics lab class. The teacher said it takes about 20 minutes for the eye to become sensitive enough to see flashes. He said then that the eye could see a single photon. Looking around now, I confirmed that papers of the time only said that was needed no more than 10 quanta.)
So while there may be some false positives, it's not high enough to make it useless.
Someone should do the math, perhaps in the right country
it is cheaper to use mass indentured labor than
electronics.
They also tend to be good at making cheap electronics.
