Observing The Universe Really Does Change The Outcome, And This Experiment Shows How
Content: But if you lower the energy-per-photon, you'll discover that when you drop below a certain energy threshold, you don't interact with every electron. Some electrons will pass through the slits without registering which slit they went through, and you'll start to get the interference pattern back as you lower your energy. Same thing with intensity: as you lower it, the "two pile" pattern will slowly disappear, replaced with the interference pattern, while if you dial up the intensity, all traces of interference disappear. And then, you get the brilliant idea to use photons to measure which slit each electron goes through, but to destroy that information before looking at the screen. A quantum eraser experiment setup, where two entangled particles are separated and measured. No ... [+]
alterations of one particle at its destination affect the outcome of the other. You can combine principles like the quantum eraser
