Quantum simulators enable the study of strongly-correlated many-body systems that may exhibit exotic phases, such as spin liquids and supersolids. We present our progress of creating a large-scale quantum simulator at room-temperature, which is based on the nitrogen vacancy center in diamond, coupled to surrounding nuclear spins. We demonstrate the fabrication of a 1 nm thin 13C layer in diamond which is polarized and coherently controlled by the NV center. 2D-Materials which offer a clearly identifiable symmetry and thickness are transferred onto the diamond surface. The nuclear spins within the transferred flake are sensed via the NV center aiming for full polarization.
