JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]MAINZ, Germany, Oct. 21, 2020 — Researchers at Johannes Gutenberg University Mainz (JGU) successfully transported light stored in a quantum memory over a distance of 1.2 mm. The technology, once refined, could have implications for quantum memory storage. To achieve high-level storage efficiency and to extend the lifetime of the stored light, the researchers used ultracold rubidium-87 atoms as a storage medium. The light is stored via an electronically induced transparency process, in which the electric field of the incoming light is coherently transformed into an excitation of the storage medium, which, in this case,...Read full articleRelated content from Photonics MediaArticlesOptical Data Storage Dips Below the Diffraction LimitPhysicists at The City College of New York (CCNY) have developed a technique with the potential to enhance optical data storage capacity in diamonds.
