"allow magnetic excitations to talk to one another... This would allow the magnons to form a quantum computer... used two small yttrium iron garnet (YIG) magnetic spheres embedded on the circuit. This material, which supports magnonic excitations, ensures efficient and low-loss coupling for the magnetic spheres... two spheres both magnetically coupled to a shared superconducting resonator... almost a centimeter away from each other—30 times the distance of their diameters"
