Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053981-10-7475-5 Includes bibliographical references.Introduction -- Quantum memory of orbital angular momentum and its’ superposition -- Quantum memory single photon’s high-dimensional state -- Two-dimensional orbital angular momentum entanglement storage -- Raman quantum memory of high-dimensional entanglement -- Raman quantum memory polarized entanglement -- Conclusion and Outlook.This thesis presents an experimental study of quantum memory based on cold atomic ensembles and discusses photonic entanglement. It mainly focuses on experimental research on storing orbital angular momentum, and introduces readers to methods for storing a single photon carried by an image or an entanglement of spatial modes. The thesis also discusses the storage of photonic entanglement using the Raman scheme as a step toward implementing high-bandwidth quantum memory. The storage of photonic entanglement is central to achieving long-distance quantum communication based on quantum repeaters and scalable linear optical quantum computation. Addressing this key issue, the findings presented in the thesis are very promising with regard to future high-speed and high-capacity quantum communications.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Quantum opticsQuantum computersSpintronicsInformation storage and retrievalMicrowavesOptical engineeringQuantum Opticshttps://scigraph.springernature.com/ontologies/product-market-codes/P24050Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070Information Storage and Retrievalhttps://scigraph.springernature.com/ontologies/product-market-codes/I18032Microwaves, RF and Optical Engineeringhttps://scigraph.springernature.com/ontologies/product-market-codes/T24019Quantum optics.Quantum computers.Spintronics.Information storage and retrieval.Microwaves.Optical engineering.Quantum Optics.Quantum Information Technology, Spintronics.Information Storage and Retrieval.Microwaves, RF and Optical Engineering.530.1201514Ding Dong-Shengauthttp://id.loc.gov/vocabulary/relators/aut835624MiAaPQMiAaPQMiAaPQBOOK9910300543603321Broad Bandwidth and High Dimensional Quantum Memory Based on Atomic Ensembles1867770UNINA
