"error reduction/ fault tolerance performance tested, and compared with using nitride, carbide, or silicide superconducting resonators... on silicon substrates... tested at temperatures near absolute zero, demonstrated high performance, confirming feasibility for realizing low-loss quantum hardware. Loss is a critical measure of hardware quality, with lower values indicating more perfect superconducting devices"
