We analyze and characterize Wigner crystals in two-dimensional semiconductors and highlight their suitability as a platform for quantum information processing. Self-assembled crystals constitute a rich playground of quantum many-body physics. In particular, Wigner crystals are prime candidates for the realization of regular electron lattices with minimal requirements on external control and electronics. In agreement with previous works, we find that transition metal dichalcogenides (TMDs) offer an ideal platform for the observation of quantum Wigner crystals, even at finite temperature and residual disorder. Here we demonstrate how these systems can be used to investigate interacting spin networks. Owing to their unique electronic and optical properties, we find that those semiconductors may allow for an an all-optical non-destructive read-out of Wigner crystals.
