In reply to the discussion: Quantum Entanglement, Dark Counts, Coincidence Detection [View all]mindwalker_i
(4,407 posts)Long ago in school. Unfortunately I don't remember a log about it. Regardless, I kind of want to get three signals: one from each detector, and one from the coincidence circuit (two triggered pulse generators and an AND gate), and get a good feel for the percentage of enangled photons vs. non-entangled. I kind of wonder whether I can program up a PIC microcontroller to take a continuous stream from the detectors, give me total counts and percentages, and send it all to Linux. I think the pulses from the detectors are way to fast and short for a direct connection, but I could buffer it all with counters and such (as long as those are fast enough).
But after this great long discussion, I get the strong feeling that I just need to play with this stuff and screw around to get a feeling about how often there are coincindences, how filters change that, etc. Jumping right into sending beams into interferometers sounds like a recipe for frustration since it won't work, and I won't have the understanding to fix it.
