Abstract
Disclosed herein is a quantum processor comprising a substrate, a qubit structure formed on the substrate, an electroplated phonon downconversion material, and furrows through the electroplated phonon downconversion material forming a plurality of electroplated phonon downconversion islands coupled to the substrate configured to channel deposited energy away from the qubit structure. Also disclosed are methods of making and using the same.
