In the quantum world, a particle can behave like a wave and accordingly seems to be in two places at the same time. This of course is contradictory to our daily experiences with classical particles. How then should this be understood? What happens in the transitional area between the classical world and quantum mechanics? The present book answers exciting questions like these in a way that is easy to follow and to understand and is shows that the link between these two worlds will have concrete and applied effects on our daily life in the near future. It will, for example, improve and change the conventional methods of information processing. With the help of quantum cryptography, it will be possible to communicate tap-proof. Using quantum computers we will be able to solve highly complicated problems in a very short time.

"Sämtliche Aufsätze sind von hoher Qualität und überaus lesenswert. Durch die unterschiedlichen, individuellen Blickwinkel der Autoren offenbart sich die moderne Quantenphysik als offenes, aktives und spannendes Feld, in dem immer noch dieselbe Aufbruchstimmung herrscht wie in den Frühzeiten ihrer Entwicklung."
