Dr. Saif Al‑Kuwari, Director of Qatar Center for Quantum Computing (QC2) at Hamad Bin Khalifa University’s (HBKU) College of Science and Engineering (CSE) has been awarded a $740,000 Qatar National Research Fund (QNRF) grant to build an atomic quantum sensing system capable of producing precise gravity measurements.

Beginning April 2024, Dr. Al-Kuwari and colleagues will develop a prototype device for sensing variations in the earth’s gravity. The project reflects that scientists and researchers tend to rely on satellite imagery to detect such changes, despite notable concerns over accuracy. Quantum sensing technologies nevertheless provide opportunities for the research and development of ground-based gravity surveys offering highly-precise and more stable measurements. 

Precise gravity information will greatly benefit efforts to understand fluctuations caused by construction, natural resource extraction, and mineral deposits. It is also expected that key data and findings will facilitate accurate mapping of underground water currents, enhance surveying capabilities, and advance satellite-free navigation systems. Similarly, gravity data can be used to detect changes in the sea level due to polar ice melting and seismic activities, making it an extremely important tool for monitoring climate change.
