Titel: Quantum sensing and imaging with diamond spins

Abstract: Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale imaging of condensed matter and biological systems with sensitivity to single nuclear spins.  Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems, where we have imaged current flow patterns in graphene in order to reveal the transition from ohmic to electron-collision-dominated flow regimes. I will also discuss our progress towards improving the sensitivity and spatial resolution of NV-based sensing. In particular, I will present our efforts towards realizing entanglement-enhanced solid-state spin sensors and various many-body effects that can be realized in a strongly interacting spin ensembles.
