Technology Study of Quantum Remote Sensing Based on Squeezed State Light

Remote sensing has evolved as a key technology for space exploration and earth observation since its emergence in the 1960s, offering precise, macroscopic, and dynamic capabilities. Despite its advancements, challenges remain in meeting the demands for high-resolution detection due to limitations in aperture size expansion and detector performance, quantum noise posing a fundamental issue. A novel quantum remote sensing approach using optical field quantization and squeezed state light is explored to overcome these obstacles, promising enhanced imaging quality and signal-to-noise ratio. This paper presents a principle prototype of this approach, experimental outcomes, and discusses future prospects in quantum remote sensing.
