Abstract
A device has a first stack of thin films, the first stack of thin films having a first opposing surface and a first connection surface, wherein the first connection surface contacts a first superconducting region; a second stack of thin films, the second stack of thin films having a second opposing surface and a second connection surface, wherein the second connection surface contacts a second superconducting region; and a superconducting bump bond electrically connecting the first and second opposing surfaces, the superconducting bump bond maintaining a low ohmic electrical contact between the first and second opposing surfaces at temperatures below 100 degrees Kelvin, wherein at least one of the first or second superconducting regions comprise material with a melting point of at least 700 degrees Celsius.
