Hermite expansions enable closed-form computation and optimization of entanglement harvesting negativity for arbitrary temporal profiles, increasing harvested entanglement by orders of magnitude beyond second-order perturbation theory.
io-HEOM accurately captures non-Markovian waveguide QED arising from spatially non-local coupling and non-linear dispersion in different spectral densities.
