TITLE: Quantum information processing applications using ultra-fast broadband cyclical quantum memories
ABSTRACT: Quantum memories are a key aspect of present and future quantum information processing. Ideally serving as a quantum identity channel, they are necessary for quantum networks and have also featured in other intimately related applications like multiphoton state generation, quantum telescopy, and quantum key distribution. Our lab has introduced a particular quantum memory in the loop-based platform called the cyclical quantum memory. This proposal focuses on two main themes to extend this work: the development of a low-loss version of the quantum memory, and also using these quantum memories (either in their low-loss or current version) in suitable applications. These applications include (1) device certification, (2) Hong-Ou-Mandel interferometry as a precursor to entanglement swapping, and (3) a step towards quantum direct secure communication.
