✦ Synopsis

The complementarity between the interference pattern and the neutron's path through the interferometer is formulated and studied in a quantitative information theoretic way. This leads to an understanding of intermediate cases of partial knowledge of complementary quantities. The role of complementarity is also analysed for the case of interference experiments where the neutron's spin plays a crucial role and a direct connection between different classes of complementary observables is found.

Entanglement between degrees of freedom, namely between the spin, path and (total) energy degrees of freedom, for single neutrons is exploited.
