Electromagnetically induced transparency (EIT) is a promising approach for implementing quantum memory, a key component of quantum communication networks. However, its storage time is limited by decoherence, primarily due to atomic motion. Anti-relaxation coatings can mitigate decoherence by minimizing atom-wall interactions. In this study, we experimentally investigate EIT-based quantum memory in cesium vapor cells with different anti-relaxation coatings. We compare the EIT characteristics and storage behavior across different coatings to assess their suitability for quantum memory applications.
