Abstract:

Quantum metrology can be used to accelerate the search for weak signals arising from physics beyond the Standard Model. In this presentation, I will discuss quantum-enhanced sensing techniques that can be used to circumvent the quantum noise limit in searches for the axion, a well-motivated dark matter candidate. In particular, I will be focus on our recent demonstration in which we engineered a quantum non-demolition interaction to achieve an eight-fold speedup in the search for a synthetic axion signal relative to a search operated at the quantum limit.

Bio: Yue (Joyce) Jiang is a postdoctoral research associate at JILA. She received her Ph.D. in Physics from the Hong Kong University of Science and Technology in 2020, where her research focused on the nonlinear interaction between photons and laser-cooled atoms. At JILA, she has been working with Konrad Lehnert on developing quantum-enhanced sensing techniques for weak signal detection using superconducting circuits.
