摘要: Ever since the famous Bohr-Einstein dialogue,1 it has been known that is not possible in an interference experiment to have a maximum visibility pattern and path information at same time. This feature of quantum mechanics, necessary for its consistency, elevated by Feynman2 principle: whenever possible, even principle, obtain information, then one superpose probability amplitudes instead adding probabilities making experimental predictions.
