The background, quantum remote sensing needs and the current status of the development of quantum information technology are studied. The needs of practical applications development is the most pressing needs of quantum remote sensing. Basic concepts of quantum remote sensing are presented. Quantum remote sensing is the theory and methods reflected in the quantum level remote sensing of movement and the law theory reflected in remote sensing micro particles campaign. The counterpart relations and the differences between quantum remote sensing and remote sensing are presented. Information mechanism of quantum remote sensing is studied. Planck law is the basis in remote sensing physics and in accordance with the material reality of the world. For quantum remote sensing, quantum mechanics is the foundation for the next step needs to choose a practical application of the quantum of electromagnetic radiation field to study and deduct the formulas.
