Abstract: We present recent progress on several experiments performed by
our group on multi-partite and higher-dimensional quantum entanglement.
The entangled photons are produced via spontaneous parametric
down-conversion and are entangled either in their polarization and
spatial mode or in their orbital angular momentum. These multi-partite
and higher-dimensional systems serve as a resource for various quantum
information protocols such as one-way quantum computation and highly
error-tolerant quantum cryptography, respectively. We will talk about
this two specific experiments and at this occasion also give a brief
overview over other photonic experiments currently under way in our
research group.
