What YQuantum does
YQuantum GmbH is a Swiss deep-tech engineering startup founded in 2024 and operational since 2025, headquartered at Park Innovaare in Villigen, Switzerland, adjacent to the Paul Scherrer Institute (PSI). The company develops miniaturized cryogenic hardware components designed to address scaling bottlenecks in quantum computing, specifically for superconducting and spin-qubit architectures. Its product portfolio comprises three product families: BiasT components (Flux BiasT YQ-BT-2G and Cryo Flux BiasT Array YQ-CBT12-1G with 12 integrated circuits), Quantum Packaging solutions (8-port YQ-QP-8A and 20-port YQ-QP-20A sample boxes), and IR-Filters (YQ-IR-110A) manufactured using a patent-pending process, plus supporting Coldfinger & Shielding systems. Differentiated technical performance has been independently validated through academic collaborations, including 99% two-qubit gate fidelity at the University of Napoli and T1>200μs/T2>180μs coherence times at the University of Sydney.
The company operates a B2B enterprise sales motion targeting academic quantum research labs and commercial quantum hardware companies globally, with pricing structured on a custom quotation basis in Swiss Francs. Revenue is generated from hardware sales delivered FCA Villigen, supplemented by professional services covering maintenance, support, training, consultancy, and custom product development. YQuantum has established strategic partnerships with Anyon Technologies (Singapore), Rhonexum, UC Berkeley's Berkeley Quantum initiative, the University of Napoli Federico II, and the University of Sydney, and leverages PSI's cleanroom facilities for microfabrication and production. The company received a CHF 150,000 grant from Venture Kick in November 2025 and is recognized as a start-up of both ETH Zurich and the University of Basel.
