Abstract
A quantum storage device, including: a sample cryostat configured to load a storage crystal and a filter crystal and configured to cool the storage crystal and the filter crystal to a preset temperature; a laser control system configured to generate a control light and a signal light to perform a quantum storage of the signal light based on a spin population locking; a quantum state encoding and analysis system configured to perform a quantum state encoding and analysis of signal photons; and a filtering system configured to suppress noise introduced by the control light and extract the signal photons.
