Scientific assessment of the CARIOQA-PMP quantum accelerometer pathfinder

2023
Satellite gravimetry is a unique tool to monitor the Earth’s mass variations. Satellite missions like GRACE and GRACE Follow-On provide insights into the time-variable gravity field on a global scale to further improve our understanding of climate change processes and geophysical phenomena on scales of a few hundreds of kilometres. The users of gravity

Application of Quantum Optimal Control to Shaken Lattice Interferometry

American Control Conference, 2023
This paper demonstrates how quantum optimal control can be used to perform shaken lattice interferometry. The first objective is to translate the five fundamental stages of interferometry (splitting, propagation, reflection, counter propagation and ...

Quantum accelerometer: Distinguishing inertial Bob from his accelerated twin Rob by a local measurement [PDF]

Physical Review D, 2011
Single quantum system, such as Unruh-DeWitt detector, can be used to determine absolute acceleration by local measurements on a quantum field. To show this, we consider two kinematically indistinguishable scenarios: an inertial observer, Bob, measuring the field of an uniformly accelerated cavity, and his non-inertial twin Rob accelerating and making ...

Quantum-based Accelerometers for Satellite Gravimetry Missions

Accelerometers are an essential component of satellite gravimetry missions, as the non-gravitational forces acting on the satellites must be known in order to determine the Earth's gravity field. However, the accelerometers currently in use are one of the limiting factors regarding the accuracy of the determined gravity field, which opens up room for ...

Assessment of IMU Quality Requirements in Integrated Quantum Inertial Navigation Systems

2025 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)
This work presents an approach to assess the quality requirements for classical inertial measurement units (IMU) used in conjunction with a cold atom interferometer (CAI) for application in a hybrid quantum inertial navigations system (QINS).
