Artificial superconducting hybrids for low dissipation information and quantum technologies

Artificial materials composed of thin film or two-dimensional material stacks with radically different electronic and magnetic properties are a fertile ground to explore emergent unconventional states of matter [1]. Engineering and stabilising these unconventional states can lead to novel functional devices with applications in information and quantum technologies [2].

In this talk, following a brief introduction to unconventional states in thin film superconducting hybrids, I will present some recent work in our group exploring the interaction of superconductivity with ferromagnetism, non-collinear antiferromagnetism and artificial spin-ice structures. I will highlight some applications of these hybrid materials in information and quantum technologies.
