Quote: an 'and' gate only works correctly if its inputs do not change; not physically realizable because of missing reaction

Note

A logical and gate works correctly as long as its inputs do not change. "That means, however, that a physical process must here run its course with no reaction on its cause. Thus, even without the requirement that the process takes place in a very short time, we have no exact physical model available that behaves correspondingly: the and-gate does not satisfy postulate P2.
