Development of three-dimensional electro-optic systems for microwave-optical quantum transduction
ORAL
Abstract
Quantum transduction, which enables the frequency conversion between microwave and optical fields, serves as a link for interconnecting superconducting quantum systems through optical interfaces. Building on the pioneering development in three-dimensional superconducting cavity technology at Fermilab, we are advancing high-fidelity and low-noise microwave-optical transducers and exploring their applications in quantum information processing and sensing. Our work focuses on enhancing transduction efficiency in cavity electro-optic devices that integrate high-quality microwave cavities with bulk lithium niobate resonators and optical couplers. We present the results from device characterization as well as our strategies for realizing efficient optical coupling and electro-optic interactions. Additionally, we evaluate the potential of high-efficiency quantum transducers to enhance the performance of quantum sensors for applications such as dark matter detection, compared to conventional homodyne detection approaches.
