QuantaSensing Inc.

Purpose

The Project is a collaboration between QuantaSense and the National Research Council of Canada (NRC) to develop broadband, quantum-limited amplifiers (QLAs) for cryogenic radio astronomy receivers. Using kinetic inductance technology, these superconducting amplifiers will operate in the 4–12 GHz range (with potential extension to 16 GHz), targeting sub-2K noise temperatures and flat, stable gain. The Project addresses Canada’s current reliance on foreign suppliers for ultra-low-noise amplifiers by establishing a sovereign, scalable capability in quantum-limited signal amplification. The Project will begin with joint definition of performance specifications, followed by QuantaSense-led design, simulation, and cleanroom fabrication of prototype devices. Packaged amplifiers will be cryogenically tested and benchmarked by NRC against conventional HEMT-based amplifiers. Feedback will guide iterative design improvements and optimization for realworld applications. Expected outcomes include a validated QLA prototype, a documented nanofabrication process for scalable production, and comparative performance data. These will enable commercialization efforts targeting astronomy, quantum sensing, space systems, and defense technologies.
