QUANTUM GRAVIMETRY The state of the art: Earth-bound ultra-precision absolute gravimeter. Quantum interferometry makes use of the coherence of superposition states. In contrast to light, when the interference objective is cold atomic cloud, strong coupling with environment due to large polarizability, magnetic moment and scattering cross section yields today’s highest metrological sensitivity and precision. Agriculture and Food Management Water Management The availability of useable water, both surface water and groundwater, is strategically important to all levels of army enterprises. Successful execution of military operation is related to supplying sufficient water to troops and animals engaged in the field which concerns water rights of stakeholders and new detection technology to scheme more accurate water management. Quantum Tech: Laser-cooled rubidium-85 atoms are dropped in high vacuum while two-photon Raman pulses split, state switch, and recombine the atomic cloud. At the final viewport, the wavefunctions of two separate paths interfere and the populations in the ground and meta-stable ground states are measured. After several identical experiments, the absolute g-value is statistical extracted and constantly monitored where the changes in g-value refer to the water level fluctuation. The precision required to secure the future of national agriculture is around 5×10-8 of the magnitude of g-value. Direct Societal Impact: Dynamic of ground and underground water levels, global water table (LEO), drinking water management, army water security, manage short-term water conflict and peacekeeping. Collateral Advantages: Reduce poverty, raise incomes, and improve food security, long-term water management; collaboration among academics, army engineer hydrologic engineering, and the Ministry … Continue reading QUANTUM GRAVIMETRY
