... chips rapidly decreases. Once the size of individual elements reach a certain critical level, their behavior and properties are no longer governed by classical physics, but rather by quantum mechanics. Another motivation was put forward by Richard P. Feynman [Feynman, 1982], who was among the first ...

If, without in any way disturbing a system, one can predict with certainty (i.e., with probability equal to unity) the value of a physical quantity, then there exists an element of physical reality corresponding to this physical quantity. In other words, the realist believes (as most of us would) th ...
