Coherent Generation and Protection of Anticoherent Spin States
arXiv:2505.06154 · doi:10.21468/SciPostPhysCore.9.1.001
Abstract
We report the first protocol specifically designed to generate anticoherent spin- states at different orders. 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.
