| Description | The combination of cold Rydberg atoms and optical nanofibers (ONF) has the potential for creating robust quantum information devices. This thesis presents our work on the interfacing of cold 87Rb Rydberg atoms with an ONF. The first experiment examines creating Rydberg atoms near ONFs, focusing on the highest principal quantum number, n, for observable excitation and studying the behavior of nS1/2, nD3/2 and nD5/2 Rydberg states. We also present a laser locking technique that uses EIT with the Zeeman sublevels of an 87Rb Rydberg level that allows for continuous tuning over 0.6 GHz. In addition, theoretical models of state-insensitive magnetic traps for ground and Rydberg state atoms, based on a combination of ONF light-induced and external magnetic fields, as well as ONF and optical tweezers light-induced magnetic fields are developed. Finally, we present experiments on spin excitations in an ensemble of cold 87Rb atoms coupled to an optical cavity, achieving a spin-wave to single-photon conversion efficiency of χ = 0.75. These investigations strengthen the knowledge for future research on Rydberg atoms, ONFs, and optical resonators for quantum information applications. | |||||||
