This strong dipole-dipole interaction emulates spin-1/2 XXZ Hamiltonian, all parameters of which are experimentally tunable over a wide range. The chain dynamics can be followed over one second, corresponding to more than $10^4$ interaction cycles. The final state of each spin can be individually measured, and any spin-correlations between any atoms of the chain can be recovered. This enables the observation of adiabatic evolutions through quantum phase transitions, of sudden quenches, and fast modulations of the interaction parameters. The proposed circular-Rydberg-atom quantum simulator should open the way towards the simulations of systems and of their dynamics beyond the grasp of classical computation[1].
