Abstract
Here, I discuss the potential of developing exquisite quantum simulators composed of van der Waals heterostructures and the moiré superlattices that emerge in such materials. I outline several practical steps needed to realize such exciton quantum simulators: (1) tunable trapping potentials, (2) precise initialization of single excitations per trap, (3) tunable interaction parameters, (4) single excitation readout. Notably, these steps parallel the early stages of development in several existing quantum simulator technologies. In discussing this outlook, I simultaneously highlight our own experimental results that aim to demonstrate some of these foundational steps. While our measurements indicate several promising avenues for future technologies, I speculate that - perhaps most importantly - our results establish moiré superlattices as a promising next generation quantum simulator architecture.
