Numerical simulations of strongly correlated quantum many-body systems are becoming intractable for as few as <100 particles. This gave rise to the idea of quantum simulation to gain access to nonequilibrium mechanics of large systems. As solid state system for our quantum simulator experiments we use a dense layer of C13 nuclear spins inside an otherwise C12-enriched bulk diamond. Initialization, control and read-out of this spin array is accomplished with nitrogen-vacancy (NV) centers implanted in the diamond. The system stands out due to exceptional long coherence times even at room temperature. Using nuclear magnetic resonance techniques we can control the dipole-dipole interaction between the nuclear spins in the 2D ensemble. This will allow us to simulate a wide variety of strongly correlated spin models.
