摘要： A method of forming a superconductor structure is disclosed. The method comprises forming a superconductor line in a first dielectric layer, forming a resistor with an end coupled to an end of the superconductor line, and forming a second dielectric layer overlying the resistor. The method further comprises etching a tapered opening through the second dielectric layer to the resistor, and performing a contact material fill with a normal metal material to fill the tapered opening and form a normal metal connector coupled to the resistor.

摘要： Systems and methods are provided for a tunable transmon qubit. The qubit includes a first Josephson junction on a first path between a transmission line and a circuit ground and second and third Josephson junctions arranged in parallel with one another on a second path between the transmission line and the circuit ground to form a direct current superconducting quantum interference device (DC SQUID). The DC SQUID is in parallel with the first Josephson junction. A capacitor is arranged in parallel with the first Josephson junction and the DC SQUID on a third path between the transmission line and the circuit ground as to form, in combination with the first path, an outer loop of the tunable transmon qubit. A bias circuit is configured to provide a constant bias flux to one of the DC SQUID and the outer loop of the tunable transmon qubit.

摘要： One example includes a magnetic flux source system that includes a tunable current element (50). The tunable current element includes a SQUID (52) inductively coupled to a first control line (54) that conducts a first control current that induces a bias flux in the SQUID to decrease relative energy barriers between discrete energy states of the tunable current element. The system also includes an inductor (LI) in a series loop with the SQUID and inductively coupled to a second control (56) line that conducts a second control current that induces a control flux in the series loop to change a potential energy of the discrete energy states of the tunable current element to set an energy state of the tunable current element to one of the discrete energy states to generate a current that provides a magnetic flux at an amplitude corresponding to the energy state of the at least one tunable current element.

摘要： An integrated circuit is provided that comprises a resistor, a first superconducting structure coupled to a first end of the resistor, and a second superconducting structure coupled to a second end of the resistor. A thermally conductive heat sink structure is coupled to the second end of the resistor for moving hot electrons from the resistor prior to the electrons generating phonons.

摘要： A solid state cooler device (10) is provided that includes a substrate (12), a first and second conductive pad (14, 16) disposed on the substrate, a first and second superconductor pad (20, 24 each having a side with a plurality of conductive pad contact interfaces (22, 26) spaced apart from one another and being in contact with a surface of respective first and second conductive pads, and a first and second insulating layer (28, 30) disposed between respective first and second superconductor pads, and respective ends of a normal metal layer (32). A bias voltage (-V, "V) is applied between one of a first conductive pad or first superconductor pad and one of the second conductive pad or the second superconductor pad to remove hot electrons from the normal metal layer, and the contact area of the plurality of first and second conductive pad contact interfaces inhibits the transfer of heat back to the first and second superconductor pads.
