    A Quantum Repeater Sandbox with Warm Atomic Memories and Quantum Dot Photon Sources
    (University of Waterloo, 2024-09-23) Li, Michael
    Quantum communication is known to offer many advantages, including opportunities for distributed quantum computing and more secure information transfer through quantum key distribution. This thesis provides background on how a quantum communication network can be achieved using quantum repeaters and how these components can be constructed with a hybrid system involving a quantum dot source and warm atomic memory. It also presents three experimental projects to realize critical components to the repeater: (1) The quantum dot photon source characterizations and tuning. (2) A compact 3D printed opto-mechanical laser locking board. (3) Optical memory observed in room temperature Cs vapor cells with an EIT memory scheme. These projects have built the basic foundation to create a repeater node using room temperature vapor cells and open the doors to future investigations of warm cell experiments.
