Flux BiasT

High Fidelity Qubit Control

YQ-BT-2G | 10 kHz – 2 GHz, 50 Ω

In Stock – Contact us for a Quote

Our specialized BiasT solution is designed to enable high-fidelity two-qubit gates on flux-tunable superconducting quantum computers. This component provides outstanding linearity and superior noise suppression.

Flux-tunable qubits are highly sensitive to control signal noise, which can be effectively filtered using our BiasT. Additionally, achieving high-fidelity control of qubit frequency requires compensating for the transient response of the control line. This precompensation depends on the system’s linearity, a characteristic that our BiasT ensures. Learn more about the importance of linerarity in our Application Note, see below

YQuantum secures 40.000 CHF from Venture Kick

YQuantum, June 24, 2025

Miniaturizing Hardware for Quantum Computing

YQuantum is solving a critical bottleneck in quantum computing: the lack of scalable cryogenic hardware. Without miniaturized, high-performance components, today’s quantum computers cannot scale into powerful, commercially viable systems for pharma, finance, and beyond.

Founded by Dr. Christian Jünger, Dr. Johannes Herrmann, and Prof. Christian Schönenberger, YQuantum brings deep expertise from UC Berkeley, ETH Zurich, and the University of Basel. The company develops compact, integrated cryogenic hardware essential for scaling quantum systems. YQuantum recently submitted its first patent, protecting a key breakthrough in the integration of microwave filters. Backed by early traction and partnerships, YQuantum is targeting a CHF 250M obtainable market within a global sector projected to reach CHF 5B by 2035.

The Venture Kick funds will help refine YQuantum’s B2B market strategy while supporting IP development and customer acquisition to solidify its position in the quantum hardware market, Read more here.
