Silent Waves
Silent Waves develops amplifiers that strengthen weak microwave signals from quantum devices while adding little noise. Its catalog spans standalone units, a compact amplifier-and-coupler package and an integrated cryogenic readout chain. The products serve the measurement layer surrounding a processor rather than acting as processors themselves.

What it does. Where it fits.
Traveling-wave parametric microwave amplifiers and integrated cryogenic readout hardware.
Who should look closer
Editorial assessment: Experimental teams comparing cryogenic readout components and balancing bandwidth, gain, saturation, installation complexity and available space.
QubitWire’s editorial assessment of practical fit.Configured products and quotations
The catalog lists Argo, Carthago, Zephyr and Dreadnought with brochure and quotation routes. The exact configuration and operating conditions should be confirmed before comparing specifications.
Check the current access route ↗What has been demonstrated
The company documents multiple amplifier and integration products. The European Commission also lists Silent Waves in SQELETON, a project to develop a combined amplifier and isolator for qubit readout.
What remains unresolved
A project award is development evidence, not a completed-product test. Amplifier gain or noise does not by itself measure processor readout fidelity; cables, loss and integration also matter.
The next question to watch
Can integrated readout arrangements retain the required noise and bandwidth in independently operated systems with repeatable calibration?
A research question, not a promised milestone.QubitWire coverage
