Improving Information Storage Time in Microwave Superconducting Circuits with Spin Ensembles

The goal of my research is to build hybrid microwave superconducting circuit systems that use spin ensembles as long-lived, coherent, quantum memories. To develop an efficient interface between the two systems, we propose coupling to the ensemble through a 3D cavity with a focused and homogeneous magnetic field mode. We plan to control the interaction between the 3D cavity and the spin ensemble through parametric coupling to a 3-wave mixing superconducting circuit element known as a SNAIL. This talk will walk through the relevant background for the two systems of interest and the parametric coupling used to interface them. Then I describe current experimental progress in designing our coupling cavity, fabricating our 3-wave mixing SNAIL element, and testing the SNAIL by using it as a parametric amplifier. Finally, I outline the experimental roadmap to realize controllable coupling between superconducting circuits and spin ensembles.
