My seventh grade daughter Emily and I have been working on a quantum erasure experiment that uses the Lego Mindstorms NXT as a mobile sensor platform for detecting photon counts (with sensors provided by www.sensl.com). We found the experiment in Scientific American. A power point presentation contains the details of our original experiment. We wanted to try the same experiment at the single photon level. Some early results are now posted.
