So ahm watchin Morgan Freeman and his universe/Wormhole stuff, and they are showing QM experiments where they are feeding/measuring SINGLE QUANTA at a time.... ie, one photon. Double slit experiments, some tuning-fork experiment at 0 deg K, some entanglement stuff....
Is it really possible to do meaningful (read: "real") experiments with single photons??? These Wormhole guys certainly think so, and I would imagine it took $millions to set these experiments up.
I mean, if we can't meaningfully pinpoint an electron, how can these guys be sure wtf is going on with a SINGLE photon??
Now, as I think about it, they seem to be able to detect particle collisions is bubble chambers, and the resulting sub-particles (incl photons, I presume), so I guess it is possible to at least detect such things.... at least in bubble chambers.
But it's hard to imagine single photons, even single electrons being *controlled* in circuits, etc. Just curious. -- EA
