Abstract:
Embodiments of the invention include a microelectronic device that includes a first silicon based substrate having compound semiconductor components. The microelectronic device also includes a second substrate coupled to the first substrate. The second substrate includes an antenna unit for transmitting and receiving communications at a frequency of approximately 4 GHz or higher.
Abstract:
Disclosed herein are qubit device packages, as well as related computing devices and methods. An exemplary qubit device package includes a quantum die and a package substrate. The face of the quantum die that houses one or more quantum circuit components is electrically connected to the package substrate by first level interconnects in the form of conductive pillars. Implementing the first level interconnects as conductive pillars allows providing sufficient distance between the quantum die and the package substrate to reduce TLS losses caused by the package substrate while, at the same time, keeping the overall footprint of the interconnects relatively small, thus providing a scalable approach to reducing quantum losses. In addition, the relatively small footprint of the conductive pillars allows providing them sufficiently close to one another to ensure improved isolation/shielding between different signal lines.

Embodiments of the invention include a microelectronic device that includes a first die having a silicon based substrate and a second die coupled to the first die. In one example, the second die is formed with compound semiconductor materials. The microelectronic device includes a substrate that is coupled to the first die with a plurality of electrical connections. The substrate including an antenna unit for transmitting and receiving communications at a frequency of approximately 4 GHz or higher.
