Detecting spin-entanglement dynamics with a quantum microscope

In a first theory part, I will present new experimentally measurable lower bounds for the two-site entanglement of the spin-degrees of freedom of many-body systems with local particle-number fluctuations. The method aims at enabling the spatially resolved detection of spin-entanglement in Hubbard systems using high-resolution imaging in optical lattices. More generally, the scheme can simplify the entanglement detection in ion chains, Rydberg atoms, or similar atomic systems. Concerning the experimental implementatioin, I will present progress towards the observation of entanglement generation and spreading during spin impurity dynamics.
