Progress on developing quantum inertial sensors in KRISS
Quantum sensors, based on the precise manipulation and control of quantum systems such as atoms, ions, and photons, are revolutionizing measurement science across a broad spectrum of applications. Leveraging mature technologies like laser cooling, and atom trapping, these sensors exploit the inherent sensitivity of quantum states to external fields and forces. This enables unparalleled precision in detecting physical quantities, including time, magnetic fields, electric fields, acceleration, and gravity. In this talk, we present the current status and challenges in the development of quantum sensors at KRISS. The institute currently operates a state-of-the-art quantum gravimeter and is developing two additional versions to achieve world-leading sensitivity. Furthermore, various efforts are underway to create field-deployable gravimeters. One such project involves a compact absolute gravimeter utilizing a novel 3D magneto-optical trap. Specifically, we employ a grating magneto-optical trap (gMOT) to enable a compact sensor design. This sensor achieves a sensitivity of 5 μm/s²/Hz¹/², making it suitable for field applications. Another key project focuses on constructing a quantum gradiometer capable of measuring gravity differences along the vertical direction. The presenstation will mainly introduce and discuss the technical advancements for the development.
