Integration of Through-Sapphire Substrate Machining with Superconducting Quantum Processors (Adv. Mater. 9/2025)
Sapphire Machining Integrated with Superconducting Qubits
In article number 2411780, Connor D. Shelly and co-workers from OQC and the University of Southampton present the integration of machining of sapphire substrates with superconducting qubits and quantum processors. It is shown that this sapphire machining process is compatible with the production of high-coherence qubits whilst maintaining tight Josephson junction parameter spread. This work provides a route to further scaling of quantum processors on sapphire.
