Abstract

This thesis details the theoretical framework and experimental realization of a hybrid quantum system coupling chiral molecules and type 2 superconductors. By utilizing coplanar waveguide resonators and transport measurements the superfluid density was probed through the shifting resonant frequency and fit to BCS theory. The pair-breaking response to increasing temperature and applied magnetic fields was used to gain insight into the behaviour of the adsorbed molecules and their contribution to the destruction of Cooper pairs. Due to additional effects from vortex formation and systematic errors in the data, the pair-breaking role of molecules could not be definitively determined. The potential emergence of triplet superconductivity upon adsorption was also explored in the low-temperature regime with a possible deviation from BCS theory identified.
