Teil 7A: Katharina Durstberger: Quantum Physics With Neutrons - Theory & Experiment (erster Teil)

Moderation: Beatrix Hiesmayr

Fundamental properties like coherence and entanglement are among the most interesting features of quantum mechanics. The physical system of interest is the neutron which is a proper object for the study of quantum mechanical behavior. An interferometer allows for quantum experiments on macroscopic scale and a polarimeter manages the neutron’s spin, one of the simplest two-level quantum system with high-efficient manipulation by magnetic fields. In combination with interferometric measurements the system has enough intrinsic richness to show remarkable quantum features. The coupling of the neutron to an external magnetic field allows for selective manipulations of the spinor quantum states and their energies. This can be used to create entangled states where the entanglement occurs between different degrees of freedom and, in addition, one can induce dephasing and decoherence by varying magnetic fields. This talk gives an overview over recent achievements in neutron interferometry.
