Introduces MPO encodings of the Magnus expansion and Dyson series for arbitrary-order accurate time evolution in 1D quantum lattices with time-dependent Hamiltonians, applicable to finite/infinite systems and long-range interactions.
Optimal cavity modulation via Krylov theory extends qubit lifetime in inhomogeneous spin ensembles by an order of magnitude over inhomogeneity and cavity losses.
