Silent Waves

Silent Waves has spun out from the Néel Institute - a CNRS laboratory in Grenoble - where it is currently hosted. The company was co-founded by Luca Planat, Nicolas Roch and Baptiste Planat with the firm intention to provide the best readout solution to its customers.

It has deep connections with the academic world and benefits from the outstanding Grenoble’s technological and scientific environment.

Silent Waves’ mission is twofold: developing cutting-edge technologies for advanced readout and providing in-depth support to its customers.

The Argo is a traveling-wave parametric amplifier based on Josephson junctions allowing near quantum-limited amplification. Based on a patented process, the Argo has all the features expected for very low power signal amplification:

• ultra-low noise
• wideband
• flux-noise immunity
• high-saturation power

The amplifier is characterized at very low temperature before shipment. It comes with an extended user manual and a summary of its measured performances.

Our founders have a large experience in the field of quantum technologies and were involved in various scientific projects. We share here a selected collection of publications focused on traveling-wave parametric amplifiers.
