Silent Waves
France · Hardware · Founded 2022 · Grenoble, France
Silent Waves manufactures traveling-wave parametric amplifiers (TWPAs) for near-quantum-limited amplification of superconducting qubit readout signals. The company's product line (Argo, Carthago, Zephyr) enables single-shot qubit readout while reducing the number of cryogenic isolators required in the readout chain. Silent Waves was spun out of Institut Néel / CNRS in Grenoble.
