SRF Cavities for Quantum Computing and Communication

Silvia Zorzetti

The next groundbreaking frontier in Quantum Information Science (QIS) involves establishing low-noise interconnections between quantum processing units (QPUs) and quantum sensors. A pivotal enabler of distributed quantum networks is high-efficiency microwave-optical transduction, a technology with broad applications.
Our research at the DOE Fermi National Laboratory and the SQMS Quantum Research Center focuses on advancing transformational technologies in quantum computing and sensing, leveraging superconducting devices with long coherence times. This talk will present a comprehensive analysis and experimental results in quantum transduction by coupling superconducting cavities to electro-optic optical cavities to achieve high conversion efficiency between microwave and optical photons. We will also explore potential implementations in quantum sensor and distributed quantum networks, enabling QPU interconnects and entanglement distribution.
