About YQuantum

YQuantum is a Swiss deep-tech startup based in Villigen that develops and manufactures hardware components for quantum computers. The product portfolio includes Quantum Packaging with 8- and 20-port sample boxes, coldfinger and shielding solutions, cryo and RT flux biasTs for precise flux biasing and noise suppression, as well as IR and low-pass filters for cryogenic microwave filtering. The components serve high-fidelity operation of superconducting and spin-qubit platforms and are designed to reduce system complexity while improving thermalization, light-tight shielding and signal integrity. YQuantum is a recognized startup of ETH Zurich and the University of Basel and has been operating since 2025. Customers and partners include Anyon Technologies, UC Berkeley, the University of Naples, the University of Sydney, ETH Zurich and the University of Basel. In May 2025, a strategic partnership with Anyon Technologies (Singapore) was announced to build scalable superconducting quantum computing systems.
