Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather. But in quantum mechanics, even if all the information is available, the outcomes of certain experiments generally can't be predicted perfectly beforehand. power. The paper looks at measurements on members of maximally entangled pairs of photons that are sent into Stern-Gerlach-type apparatus, in which each photon can take one out of two possible paths.
