Probing the Kitaev honeycomb model on a neutral-atom quantum computer.

ABSTRACT: Quantum simulations of many-body systems are among the most promising applications of quantum computers¹. In particular, models based on strongly correlated fermions are central to our understanding of quantum chemistry and materials problems², and can lead to exotic, topological phases of matter^3,4. However, owing to the non-local nature of fermions, such models are challenging to simulate with qubit devices⁵. Here we realize a digital quantum simulation architecture for two-dimensional fermionic systems based on reconfigurable atom arrays⁶. We utilize a fermion-to-qubit mapping based on Kitaev's model on a honeycomb lattice³, in which fermionic statistics are encoded using long-range entangled states⁷. We prepar
