Building upon recen t progress in Lindblad engineering for quantum Gibbs statepreparation algo rithms\, we propose a simplified protocol that is shown to be efficientund er the eigenstate thermalization hypothesis (ETH). The ETH reduces circuit overheadof the Lindblad simulation algorithm and ensures a fast convergen ce toward the targetGibbs state.

Moreover\, we show that the rea lized Lindblad dynamics exhibits resilienceagainst depolarizing noise\, op ening up the path to a first demonstration on quantumcomputers. We complem ent our claims with numerical studies of the algorithm'\;sconvergence in various regimes of the mixed-field Ising model. In line with ourpredict ions\, we observe a mixing time scaling polynomially with system size when theETH is satisfied.

In addition\, we assess the impact of algo rithmic and hardware-inducederrors on the algorithm'\;s performance by carrying out quantum circuit simulations ofour Lindblad simulation protoc ol with realistic noise models. This work bridges the gapbetween recent th eoretical advances in Gibbs state preparation algorithms and theireventual quantum hardware implementation.
