Photonic modes in cavities have been used to couple spintronic components over macroscopic distances. We explore the possibilities of coupling to superconductors in cavities. 

Remote sensing of the superconducting transition via the change in anisotropy field across a remote ferromagnetic insulator:

Geometric curvature in a magnetic material can convert conventional singlet superconducting correlations of an adjacent superconductor into spinful triplets in the magnet. These can be harnessed for low-dissipation spintronic computing, and control properties of the hybrid structure.
