Abstract
Section titled āAbstractāWe investigate a hybrid quantum system where an ensemble of nitrogen-vacancy\n(NV) centers in diamond is interfaced with a piezomagnetic superlattice that\nsupports surface phonon polaritons (SPhPs). We show that the strong magnetic\ncoupling between the collective spin waves in the NV spin ensemble and the\nquantized SPhPs can be realized, thanks to the subwavelength nature of the\nSPhPs and relatively long spin coherence times. The magnon-polariton coupling\nallows different modes of the SPhPs to be mapped and orthogonally stored in\ndifferent spatial modes of excitation in the solid medium. Because of its easy\nimplementation and high tunability, the proposed hybrid structure with NV spins\nand piezoactive superlattices could be used for quantum memory and quantum\ncomputation.\n
