- Abstract
The storage of quantum states and information is essential for enabling large quantum networks. The direct implementation of storage in magnonic systems, which are emerging as crucial components in quantum networks, has also garnered attention. In this study, we present experimental investigations of magnomechanical microwave storage for the first time. By reducing the ambient temperature to 8 K, we can achieve a mechanical mode with a narrow linewidth as low as 6.4 Hz, resulting in an energy decay time of 24.8 ms. Furthermore, we employ Ramsey interferometry to investigate the coherence of the magnomechanical memory. The mechanical interference can be utilized to evaluate the decoherence lifetime of 19.5 ms. Our proposed scheme provides the potential to utilize magnomechanical systems as quantum memory for photonic quantum information.
