SQMS Study Links Qubit Performance to Material and Fabrication Features
The SQMS Center has reported a study linking variation in superconducting qubit performance to features of the materials and fabrication processes used to build them. The work treats coherence retention as the key property determining whether a qubit can hold and process information in advanced computations.
Within two years, superconducting qubit fabricators could begin using material and fabrication signatures as early screening metrics, allowing them to identify low-coherence devices before costly cryogenic testing.
