The concept introduces a miniaturized lidar receiver integrating photonic chips with second-order interferometers and superconducting or room-temperature single-photon detectors to enable high-precision wind measurements from space. It leverages phase-squeezed light sources and quantum interference effects such as the Hong-Ou-Mandel effect to surpass traditional rover or helicopter-based atmospheric sensing methods, targeting planetary atmospheres like Mars for enhanced entry, descent, and landing modeling.
While still in initial development phases including bench demonstrations and theoretical framework establishment, the approach promises capabilities for global-scale, high-altitude wind profiling on Mars and potential applications on Earth and other planetary bodies. This quantum lidar could significantly aid climate monitoring, aviation safety, and understanding of dynamic atmospheric environments in extreme conditions.
