Quantum-enhanced optomechanical accelerometer
Photonics ResearchAcceleration sensing, an essential branch of quantum sensing, faces a fundamental trade-off between resolution and bandwidth. Here, we present a quantum-enhanced optomechanical accelerometer (QEOMA), simultaneously achieving the improvement of the sensing resolution and bandwidth in contrast with a classical counterpart.

A three-axis quantum accelerometer for mobile sensing applications
Cold Atoms for Quantum Technologies, 2020We present a mobile 3D accelerometer based on matter-wave interferometry, which is capable of measuring three orthogonal accelerations, each with respect to an independent inertial reference frame defined by the surface of a mirror. On each axis, we construct a hybrid quantum/classical accelerometer by using correlations between the atoms and a ...

Oscillator-free quantum accelerometer with multi-bandwidth via memory
Photonics Research, 2022 The accelerometer plays a crucial role in inertial navigation. The performance of conventional accelerometers such as lasers is usually limited by the sensing elements and shot noise limitation (SNL). Here, we propose an advanced development of an accelerometer based on atom–light quantum correlation, which is composed of a cold atomic ensemble, light ...

Quantum theory of fluctuations in a cold damped accelerometer [PDF]
European Physical Journal D, 2000 We present a quantum network approach to real high sensitivity measurements. Thermal and quantum fluctuations due to active as well as passive elements are taken into account. The method is applied to the analysis of the capacitive accelerometer using the cold damping technique, developed for fundamental physics in space by ONERA and the ultimate ...
