The protocol consists of cycles of a rotation pulse about an axis followed by a squeezing pulse in a perpendicular direction. To protect these states, we develop dynamical decoupling techniques using group-based sequence design and the dynamically corrected gate formalism. We analyze key sources of dephasing, disorder, and dipole-dipole interactions and assess the effectiveness of our methods in preserving coherence. Potential applications of the produced anticoherent spin states include quantum sensing and studies related to quantum entanglement. × TY - JOURPB - SciPost FoundationDO - 10.21468/SciPostPhysCore.9.1.001TI - Coherent generation and protection of anticoherent spin statesPY - 2026/01/12UR - https://scipost.org/SciPostPhysCore.9.1.001JF - SciPost Physics CoreJA - SciPost Phys.
