Thulium Doped Garnets for Quantum Repeaters and Optical Quantum Memory

Quantum memories will prove to be an invaluable tool for distributing entangled quantum states over distance. Many novel materials for this purpose are being investigated and key among them are rare earth ion doped crystals. These materials possess a great number of potential combinations of host crystal and ion species for further study, some of which will likely be used to create the first quantum repeaters. Choosing a specific combination, thulium doped garnets, and a unique goal of making memory devices which can function simultaneously across many spectral channels, I take a unique perspective through which to push the performance of quantummemories ...
