| contents | We propose a dissipative protocol for preparing nonequilibrium steady-state entanglement in neutral atom arrays within a Floquet-Lindblad framework. Stabilizer pumping is implemented through noninstantaneous kicks, where each period consists of a short resonant laser pulse followed by a detuned strong $π$ pulse that couples the atomic ground state to a Rydberg state. This scheme is intrinsically fast and robust against the Doppler shifts and interatomic spatial fluctuations, as adiabatic requirements on the laser field are avoided. As such the engineered dissipation channels induce a fast decay rate, dramatically accelerating convergence toward the desired steady states. We show that this approach is inherently scalable and enables high-fidelity preparation of arbitrary multipartite graph states in the neutral atom array at zero and finite temperatures. Our study not only facilitates the preparation of resource states for measurement-based quantum computation but also provides a passive error-correction mechanism in the undergoing computation. |
