Commitment to quality

Quality is an important focus at ID Quantique. All our detectors are built, tested, and characterized at our headquarters in Geneva, Switzerland with inspections and performance verification at every stage, while our superconducting nanowire wafers are fabricated in state-of-the-art cleanroom facilities in Lausanne, Switzerland.

We follow robust quality control protocols including ISO 9001 standards compliance. Customers can be confident our detectors will meet their demanding application requirements due to our experienced engineering staff, industrialized manufacturing process, and dedication to continuous improvement over decades of detector production. With low defect rates and strong warranties, we stand behind the reliability and quality of our single-photon detection solutions.
