Engineering quantum entanglement by coherent Rydberg dressing
Abstract/Contents
- Abstract
- Ensembles of neutral atoms enable state-of-the-art measurements of time, acceleration, and electromagnetic fields. Introducing entanglement among the constituent atoms offers a route to enhancing the precision of these measurements. One proposed approach to generating the requisite entanglement relies on the off-resonant optical coupling of one ground state to a highly excited electronic state. This technique, known as Rydberg dressing, enables local and dynamical control of interactions between neutral atoms. In this thesis, I present the engineering of Rydberg-dressed interactions by single-photon coupling to nP states in a cesium atomic clock. Optimizing the coherence of these many-body interactions is a major challenge; in order to understand and minimize dissipation mechanisms, I show sensitive measurements of percent-level noise processes, comparable to the projection noise of our atomic ensembles. Finally, I present the creation of a squeezed spin state by local interactions that achieves a factor of 0.79(6) reduction in phase variance below the standard quantum limit. The results of this thesis seek to inform the design of future experiments that will use coherent Rydberg-dressed interactions for a wider range of applications in quantum sensing and simulation.
