Quantum Sensing by Using STIRAP with Dressed States Driving

Abstract

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.

A shortcut tour of quantum control methods for modern quantum technologies

“…We have used the described STA method in order to maximize entanglement between coupled spins [51] and in a bosonic Josephson junction [57], while we have evaluated its performance for the three-level STIRAP system under the presence of Ornstein-Uhlenbeck noise processes in the energy levels [58]. Other recent works exploit the advantages of this method or its generalizations for quantum state transfer [59][60][61], quantum computation [62][63][64], and sensing [65]. Note that the presented STA method is a specific example of the more general inverse engineering method [12,17,66,67], where the quantum trajectory is prescribed first, eq.…”
