Quantum metrology using large ensembles of entangled atoms
Abstract/Contents
- Abstract
- Atomic sensors are pushing the boundaries in precision for timekeeping, magnetometry, and gravity gradiometry. Conventional atomic sensors are ultimately limited by the quantum projection noise. In this thesis, the quantum projection noise limit on sensing precision is circumvented by exploiting entanglement—quantum correlations between the atoms. Entangled states enabling 100-fold measurement precision enhancement were generated using cavity-based measurements. Additionally, a new method was developed which allows entanglement-enhanced metrology without detection noise beyond the quantum projection noise limit.
