Abstract

Diffraction on the slit can be interpreted in accordance with the Heisenberg uncertainty principle. This elementary example hints at the importance of the information theory for the quantum physics. The role played by one particularly interesting measure of information -- the Fisher information -- in quantum measurements is further discussed in the context of quantum interferometry.
