Scientific advances supporting the growth of our nation’s information infrastructure presently derive exclusively from features of classical physics. But in recent years, a new framework has emerged to develop information technologies that operate according to the more fundamental laws of quantum physics. The intersection of quantum physics with information theory has led to quantum information...

In contrast to the Copenhagen interpretation we consider quantum mechanics as universally valid and query whether classical physics is really intuitive and plausible.-We discuss these problems within the quantum logic approach to quantum mechanics where the classical ontology is relaxed by reducing metaphysical hypotheses. On the basis of this weak ontology a formal logic of quantum physics can...
