  EC signature

  The European Innovation Council (EIC) has awarded Silent Waves a grant for their groundbreaking project SQELETON. The project aims to push further the traveling wave parametric amplifier isolator technology towards a commercial product.

Sqeleton is led by Silent Waves

Providing the most advanced readout experience

Silent Waves is a spin-off from the Institut Néel, one of the largest CNRS research laboratories with recognized expertise in quantum electronics, superconductivity, and fabrication of quantum devices. Based in Grenoble, the company is embedded within a world-class innovation ecosystem that combines outstanding science and technology with a dynamic startup scene. Silent Waves was co-funded by Luca Planat, Nicolas Roch and Baptiste Planat to advance the development of cutting-edge technologies in order to provide the most advanced readout solution for its customers, together with comprehensive expert support. 

Supporting deeptech and fundamental research

Promising research fields such as quantum computing, radio astronomy and electron spin resonance depend on the accurate detection of ultra-low power microwave signals. Advanced microwave signal readout, involving sophisticated readout hardware and expertise, is required in order to achieve the necessary accuracy. With our products and our in-depth customer support, we enable companies and research teams to focus on their core work.
