Quantum Sensing by Using STIRAP with Dressed States Driving

Exploring quantum technology to precisely measure physical quantities is a meaningful task for practical scientific researches. Here, we propose a novel quantum sensing model based on dressed states driving (DSD) in stimulated Raman adiabatic passage. The model is universal for sensing different physical quantities, such as magnetic field, mass, rotation and etc. For different sensors, the used systems can range from macroscopic scale, e.g. optomechanical systems, to microscopic nanoscale, e.g. nitrogen-vacancy color centres in diamond. By investigating the dynamics of color detuning of DSD passage, the results show the sensitivity of sensors can be enhanced by tuning system with more adiabatic and accelerated processes in non-degenerate and degenerate color detuning regime, respectively. To show application examples, we apply our approach to build optomechanical mass sensor and solid spin magnetometer with practical parameters.
