• Abstract summary: We discuss the design of quantum hybrid inertial sensor that combines an optomechanical inertial sensor with the retro-reflector of a cold atom interferometer. This sensor fusion approach provides absolute and high accuracy measurements with cold atom interferometers. We evaluate which parameters yield an optimal acceleration sensitivity, from which we anticipate a noise floor at nano-g levels from DC to 1 kHz.

• Abstract: We discuss the design of quantum hybrid inertial sensor that combines an optomechanical inertial sensor with the retro-reflector of a cold atom interferometer. This sensor fusion approach provides absolute and high accuracy measurements with cold atom interferometers, while utilizing the optomechanical inertial sensor at frequencies above the repetition rate of the atom interferometer. This improves the overall measurement bandwidth as well as the robustness and field deployment capabilities of these systems. We evaluate which parameters yield an optimal acceleration sensitivity, from which we anticipate a noise floor at nano-g levels from DC to 1 kHz.

  Quantum sensors based on solid-state defects, in particular nitrogen-vacancy centers in diamond, enable precise measurement of magnetic fields, temperature, rotation, and electric fields. We introduce a cavity quantum electrodynamic (cQED) hybrid system operating in the strong coupling regime, which enables high readout fidelity of an NV ensemble. We demonstrate a broadband sensitivity of 580 fT/$sqrtmathrmHz$ around 15 kHz in ambient conditions.

  Optomechanical systems have been exploited in ultrasensitive measurements of force, acceleration, and magnetic fields. We show that joint force measurements taken with entangled probes on multiple optomechanical sensors can improve the bandwidth in the thermal-noise-dominant regime. The demonstrated entanglement-enhanced optomechanical sensing could enable new capabilities for inertial navigation, acoustic imaging, and searches for new physics.

  Defects in solid state materials provide an ideal platform for quantum sensing.

We experimentally demonstrate that we can overcome these challenges using Floquet theory and optimal control optimization methods.
