Abstract
Quantum-based sensing and measurement technology is a disruptive technology that can realize fine detection of the gravity and magnetic fields in deep Earth, and it has become a key development direction for geophysical exploration equipment worldwide. This study focuses on the frontier technologies for the quantum-based high-precision measurement of Earth’s gravity and magnetic fields, summarizes the development status of quantum-based geophysical exploration equipment, and analyzes demand for the superconducting quantum-based electromagnetic detection system, magnetic vector gradient detection system, superconducting gravity detection system, and cold-atom absolute-gravity exploration system during deep resource exploration. Moreover, the international trend of quantum-based high-precision measurement technology as well as the development opportunities and challenges in this field are analyzed. To improve the core technology research, complete localization, and exploration application of quantumbased geophysical exploration equipment in China, we propose the development goals, technical system, key tasks, and strategic planning for a new generation of quantum-based high-precision deep geophysical exploration equipment. This aims to achieve breakthroughs in superconducting quantum chips and high-sensitivity sensors, establish a collaboration model for the independent development of China’s quantum-based geophysical exploration equipment, promote the high-quality development of deep exploration equipment, and provide strategic support for solving major problems associated with deep mineral resource exploration and revealing of Earth’s deep structure.
