Abstract: A thermalization structure is formed using a cover configured with a set of pillars, the cover being a part of a cryogenic enclosure of a low temperature device (LTD). A chip including the LTD is configured with a set of cavities, a cavity in the set of cavities having a cavity profile. A pillar from the set of pillars and corresponding to the cavity has a pillar profile such that the pillar profile causes the pillar to couple with the cavity of the cavity profile within a gap tolerance to thermally couple the chip to the cover for heat dissipation in a cryogenic operation of the chip.

Abstract: Eine Quantenbit(Qubit)-Flip-Chip-Baugruppe wird gebildet, wenn ein Qubit auf einem ersten Chip gebildet wird und ein optisch durchlässiger Weg auf einem zweiten Chip gebildet wird. Die beiden Chips werden unter Verwendung von Lothöckern gebondet. Der optisch durchlässige Weg sorgt für einen optischen Zugang zu dem Qubit auf dem ersten Chip.

Abstract: Systems and techniques that facilitate hybrid readout packaging for quantum multichip bonding are provided. In various embodiments, an interposer can have a first quantum chip and a second quantum chip. In various aspects, a readout resonator (e.g., input/output port) of one or more qubits on the first quantum chip can be routed to an inner portion of the interposer. In various instances, the inner portion can be located between the first quantum chip and the second quantum chip. In various aspects, routing the readout resonator to the inner portion can reduce a number of crossings and/or intersections between input/output lines on the interposer and connection buses between qubits on the interposer.

Abstract: On a first superconducting layer (316) deposited on a first surface of a substrate (312), a first component of a resonator is pattered. On a second superconducting layer (326) deposited on a second surface of the substrate (312), a second component of the resonator is patterned. The first surface and the second surface are disposed relative to each other in a non-co-planar disposition. In the substrate, a recess is created, the recess extending from the first superconducting layer to the second superconducting layer. On an inner surface of the recess, a third superconducting layer (322) is deposited, the third superconducting layer forming a superconducting path between the first superconducting layer and the second superconducting layer. Excess material of the third superconducting layer is removed from the first surface and the second surface, forming a completed through-silicon via TSV (320).

Abstract: A quantum computing device includes a first chip having a first substrate and one or more qubits disposed on the first substrate. Each of the one or more qubits has an associated resonance frequency. The quantum computing device further includes a second chip having a second substrate and at least one conductive surface disposed on the second substrate opposite the one or more qubits. The at least one conductive surface has at least one dimension configured to adjust the resonance frequency associated with at least one of the one or more qubits to a determined frequency adjustment value.

Abstract: Ein Stapel aus einer Hartmaskenschicht, einer Weichmaskenschicht und einem Photoresist wird auf einem Substrat gebildet. Der Photoresist wird strukturiert, so dass er mindestens eine Öffnung umfasst. Die Struktur wird durch ein anisotropes Ätzen in die Weichmaskenschicht übertragen, wodurch ein kohlenstoffreiches Polymer gebildet wird, welches mehr Kohlenstoff als Fluor umfasst. Das kohlenstoffreiche Polymer kann durch Verwenden eines Fluorkohlenwasserstoff enthaltenden Plasmas gebildet werden, welches mit Fluorkohlenwasserstoff-Molekülen gebildet wird, die mehr Wasserstoff als Fluor umfassen. Die Seitenwände der Weichmaskenschicht werden mit dem kohlenstoffreichen Polymer beschichtet und dieses verhindert eine Verbreiterung der Struktur, die in die Weichmaske übertragen wird. Der Photoresist wird anschließend entfernt und die Struktur in der Weichmaskenschicht wird in die Hartmaskenschicht übertragen. Seitenwände der Hartmaskenschicht werden mit dem kohlenstoffreichen Polymer beschichtet, um eine Verbreiterung der Struktur zu verhindern, die in die Hartmaske übertragen wird.
