| contents | The Lotka-Volterra model is a paradigm for self-organized predator-prey oscillations in far-from-equilibrium systems, yet testing it in real-world ecosystems is hindered by uncontrollable microscopic parameters. Here, we propose a quantum analogue of predator-prey dynamics using a tunable two-dimensional Rydberg atom array. Through mean-field analysis and numerical simulations based on the open-system discrete truncated Wigner approximation, we demonstrate that Rydberg excitations exhibit predator-prey cycles on microsecond timescales. We show that quantum coherence drives spontaneous symmetry breaking, while long-range interactions stabilize global oscillations against quantum-noise-induced desynchronization. We further reveal that quantum jump induce quasicycles whose amplitude scales inversely with the square root of the system size. Our work extends the study of predator-prey models to the quantum realm and advances quantum simulation stratagies that leverage engineered many-body nonequilibrium effects. |
