lightstoring
Lightstoring refers to the ability to capture a light signal and retain its information for a finite period within a medium or device, after which the light can be released with its properties largely preserved. In practice, light storage is most often discussed in the context of optical or quantum memory, where a photon's quantum state is mapped onto material states, such as atomic coherences or spin orientations, and later reconstructed as a light pulse.
Common approaches use electromagnetically induced transparency (EIT) in ensembles of atoms or solid-state analogues to slow
Realizable platforms include warm or cold alkali atomic vapors, rare-earth-doped crystals, and engineered solid-state devices. Storage
Applications include quantum communication networks and quantum repeaters, where light storage enables synchronization of probabilistic photon
Research in light storage aims to extend storage time, increase multimode capacity, operate at telecom wavelengths,
