Testing kinetic inductance traveling-wave parametric amplifier (KITWPAs) for quantum sensing applications

Qubic Technologies, specializes in developing advanced quantum microwave transmitters and receivers for remote sensing and telecommunications applications [1]. They leverage superconducting quantum circuits composed of Josephson junctions to enable the generation of entangled microwave signals with correlations beyond classical limits [2]. Their mission is to enable clients to acquire and transmit sensitive data with unprecedented detail, even in challenging environments.
In this research project, we aim to integrate a kinetic inductance traveling-wave parametric amplifier (KITWPAs) [3] into a quantum microwave radar system to enhance sensitivity and resolution. KITWPAs amplifiers, known for their near-quantum-limited noise performance, high saturation power and ultra-low heat dissipation, can significantly improve the detection of weak microwave signals in radar applications. By leveraging quantum materials and ultra-low-noise amplification, this study will explore the feasibility of using quantum amplifiers to detect low-reflectivity targets in simulated radar experiments in the laboratory. If successful, positive outcomes of this project will allow us to push the boundaries of quantum-enhanced sensing and will provide a step-change in sensitivity for very wide range of critical remote sensing systems in several applications including air traffic control, defense and security of compounds and airspaces, and satellite imaging to survey climate change effects.
