Hidden context

摘要

The idea that physical phenomena might be described by a more down-to-earth theory than quantum physics has met with resistance from many physicists. Indeed, it seems that nature is not as simple as we would like.rnQuantum mechanics is weird, there is no doubt about that. Efforts to demystify this theory and reconcile it with the laws of classical physics have led to the development of theories of hidden local variables - the hypothetical parameters of a quantum system that govern the seemingly random outcomes of quantum measurements. As it turns out, these theories require quantum mechanics to be non-contextual: the results of measurements on a quantum system should not depend on the act and specific properties (the context) of the measurement process itself; they should be set prior to it.
