Distributed Quantum Computing and Networking with Trapped Ions - Jungsang Kim

Construction and operation of a distributed quantum network can enable exciting applications such as scalable quantum computer and long-distance secure quantum communication systems, but remains a major experimental challenge. Practical realization of a quantum network can be accomplished by the integration of high quality quantum memories and quantum information processing elements with photonic communication channels. Other than identifying physical quantum systems to implement the qubits and logic operations, new protocols for maintaining quantum coherence through a range of quantum operations, classical controllers that keep track of quantum coherence, and new enabling technologies to bridge the hybrid quantum systems are required. I will describe main challenges and ideas for research directions in enabling practical quantum networks, and discuss examples of relevant research efforts in trapped ion and single photon experiments. Specifically, experimental progress in trapped ion systems in microfabricated traps will be presented.
