SkyWater and QuamCore to co-develop a fabricated single-flux-quantum digital controller for superconducting qubits
On 2025-11-06 SkyWater Technology and QuamCore announced a collaboration to co-engineer a superconducting fabrication process integrating single-flux-quantum (SFQ) digital control circuits with superconducting qubit arrays, aiming to cut wiring density, heat load and latency versus CMOS control. The partners cite up to nine orders of magnitude lower control-power consumption and a roadmap toward million-qubit systems, with 12-18-month milestones for superconducting test vehicles and wafer-scale SFQ control chips. Disclosed via press.
A U.S.-foundry plus quantum-control-startup process-development partnership targets the cryogenic-control-wiring bottleneck that constrains superconducting-qubit scaling; it is an early-stage development collaboration with multi-quarter milestones rather than a delivered product, placing it low in the band.
Domestic SFQ-control fabrication would strengthen the U.S. quantum supply chain and SkyWater's positioning as a quantum-hardware foundry; execution risk centers on integrating SFQ logic with qubit arrays at wafer scale.
