Zusammenfassung:In an embodiment, a quantum device includes a first set of protrusions formed on a substrate and a second set of protrusions formed on a qubit chip. In the embodiment, the quantum device includes a set of bumps formed on an interposer, the set of bumps formed of a material having above a threshold ductility at a room temperature range, wherein a first subset of the set of bumps is configured to cold weld to the first set of protrusions and a second subset of the set of bumps is configured to cold weld to the second set of protrusions.
