What is the difference of observing the double slit experiment - once with our eyes and once with a special device?
We perceive the interference image if we not observe the situation near the slit, and just 2 stripes if we do. What is the difference in the observing? Don't we still observe the electrons in both ...
Is the beta barium borate crystal an observer in the delayed choice quantum eraser double split experiment?
I'm a little confused about the top answer to this question: Variation of delayed choice quantum eraser He says "if you simply detect all signal photons and make no distinction between them, there ...
Ok so if we setup a camera before the slit we will find a single photon and will follow through accordingly, likewise by having a camera setup after the slit, we can retroactivly collapse the wave ...
I understand that in the single-electron-at-a-time double slit experiment, if a detector is placed before the slit, the interference pattern vanishes. Suppose I left the detector on, but put a bag ...
Wave-particle duality states that a particle has both wave properties and particle properties when one is not observing it. 1) What is an observer? Need it be anything living or can other particles ...
