• Abstract: Entanglement is a key resource for quantum technologies. We show that protocols employing quantum Mpemba effects allow one to exponentially accelerate the generation of entanglement, or to slow down the decay thereof. Two entanglement Mpemba effects with different operational meaning are introduced, focusing either on the task of rapidly generating a certain threshold value for entanglement or on achieving the asymptotic steady-state value. We show that entanglement Mpemba effects depend on the chosen entanglement measure. Using cluster elimination methods, many-body quantum systems also benefit from the exponential speedup of entanglement generation, as we demonstrate for a dissipative long-range Ising chain.
