We present quantitative predictions for quantum simulator experiments onIsing models from trapped ions to Rydberg chains and show how thethermalization, and thus decoherence times, can be controlled by consideringcommon, independent, and end-cap couplings to the bath. We find (i) independentbaths enable more rapid thermalization in comparison to a common one; (ii) thethermalization timescale depends strongly on the position in the Ising phasediagram; (iii) for a common bath larger system sizes show a significant slowdown in the thermalization process; and (iv) finite-size scaling indicates asubradiance effect slowing thermalization rates toward the infinite spin chainlimit. We find it is necessary to treat the full multi-channel Lindblad masterequation rather than the commonly used single-channel local Lindbladapproximation to make accurate predictions on a classical computer. This methodreduces the number of qubits one can practically classical simulate by at leasta factor of 4, in turn showing a quantum advantage for such thermalizationproblems at a factor of 4 smaller qubit number for open quantum systems asopposed to closed ones. Thus, our results encourage open quantum systemexploration in noisy intermediate-scale quantum technologies.
