We fabricate and characterize superconducting through-silicon vias and electrodes suitable for superconducting quantum processors. We measure internal quality factors of a million for test resonators excited at single-photon levels. on chips with superconducting vias used to stitch ground planes on the front and back sides of the chips. This resonator performance is on par with the st... https://parisnaturalfoodes.shop/product-category/baby-unscented-body-soap/
