"Exploring new frontiers of quantum science with hybrid systems"
Remarkable progress in working with quantum bits in a wide variety of systems, combined with improvements in our understanding of small-scale quantum systems, leads to the possibility of interface disparate systems at the quantum mechanical level. This allows using the best characteristics of each subsystem to enable new technology and scientific exploration. For example, photons provide a good quantum degree of freedom, with long coherence times, easy manipulation using linear optical elements, and the potential for high-efficiency detection. At the same time, spins in solids have remarkable possibilities for quantum gates and quantum memory. I will discuss recent advances towards implementation of nonlinear photonic and phononic devices for quantum information processing and quantum simulation of topological phases of matter. For example, I will consider implementation of a quantum simulator for topological states of matter using light, methods of doing ultra-high sensitivity, high bandwidth, self-calibrated acceleration sensing, quantum transduction of radio frequency photons to optical photons, and the direct coupling of individual electron spins to microwave and optical photons. These advances may lead to new approaches for quantum information processing, quantum communication, and quantum-limited metrology.
