We propose an optical model in which both quantum and quasi-classical states can be ideally stored using coupled resonators. The protocol is based on a time-dependent coupling between two cavities, carefully modulated to allow the complete transfer of an external propagating field from one cavity to another. The system maintains high storage efficiency (above 99.99%) even when error sources are introduced (up to 5%) in the coupling, such as amplitude deviation or a time delay between field propagation and coupling control. Furthermore, this procedure can be extended to store entangled states by considering either a pair of systems or bimodal cavities. Due to its high efficiency, this model may find application in current quantum technologies, such as quantum memories and quantum batteries, which rely on efficient quantum state storage.
