Socket Test Architecture for Reducing Spurious modes

Parasitic electromagnetic resonances

A particular challenge is the presence of “box modes”-parasitic electromagnetic resonances that can form inside metallic housings. These modes can couple to quantum circuits, degrading coherence and reducing measurement fidelity. Understanding and mitigating these effects is essential for achieving reliable, scalable quantum hardware performance.

Combining modelling and testing expertise

STARS combines TNO’s expertise in microwave and cryogenic system modelling with OrangeQS’s leading capabilities in quantum device testing. Together, the partners will develop accurate simulation workflows, test multiple enclosure geometries, and derive design rules that suppress harmful modes and other EM related disturbances.

Strengthening the Dutch quantum technology position

The project ultimately equips the Dutch quantum technology ecosystem with foundational knowledge for next generation quantum testing systems. By improving coherence protection and measurement reliability, STARS supports faster innovation cycles and strengthens the Netherlands’ position in the global quantum hardware value chain.
