Exploring Quantum Harmony between Superconducting Circuits & Cold Atoms.

Speaker: Yue (Joyce) Jiang,  JILA, University of Colorado Boulder

Abstract: Join me in this talk as I share my research journey in quantum information science, transitioning from cold atoms to superconducting circuits and exploring their harmonious collaboration in advancing quantum science and technology. In the first part, I will discuss the demonstration of a quantum-enhanced sensing technique at microwave frequencies using superconducting circuits to accelerate the search for weak signals arising from physics beyond the Standard Model, with a specific focus on axion dark matter searches. Shifting gears in the second part, we will delve into quantum optics experiments that utilize the nonlinear interaction between the cold atomic ensemble and optical photons, unveiling the fascinating realm of non-Hermitian quantum optics. Wrapping up, we will explore the exciting science that leverages the strengths of both systems, utilizing superconducting-atomic hybrid systems to bridge the gap between quantum information science in microwave and optical frequencies.
