• Abstract: We report the first protocol specifically designed to generate anticoherent spin-$j$ states at various orders. The protocol consists of cycles involving a rotation pulse about one axis, followed by a squeezing pulse along a perpendicular direction. To protect these states from decoherence, we develop dynamical decoupling techniques based on group-theoretic sequence design and the dynamically corrected gate formalism. We analyze key sources of dephasing, disorder, and dipole-dipole interactions, and evaluate the effectiveness of our methods in preserving coherence. Potential applications of the generated anticoherent spin states include quantum sensing and studies of quantum entanglement.
