Exploiting the nature of quantum phenomena, quantum technologies are developing rapidly towards computing, communicating, and sensing. Quantum inertial sensors based on light-pulse atom interferometry are powerful tools for fundamental physics, metrology, navigation, geoscience, and civil engineering. By contrast to classical sensors, atom interferometers use photon momentum to coherently split and recombine matter waves. Since laser wavelength defines photon momentum with high precision, atom interferometers are accurate and are thus ideal sensors for precision measurements. In this talk, I will present mobile, versatile, and sensitive atom interferometers for multiaxis acceleration and rotation measurements and mobile gravimetry in the field. With simplicity and sensitivity, our technology paves the way for bringing quantum sensors to field applications.


Dr. Xuejian Wu joined the Department of Physics at Rutgers University-Newark as an Assistant Professor in January 2021. Wu was a Postdoctoral Scholar in Department of Physics at the University of California, Berkeley. There he developed developed mobile quantum accelerometers and gyroscopes using light-pulse atom interferometry, and applied them for geological surveys. Wu received his PhD at Tsinghua University in 2015 and Bachelor’s Degree at Beijing Jiaotong University in 2009.
