Towards Photon-Mediated Creation of Twin Fock States in an Optical Resonator
Abstract/Contents
- Abstract
- This thesis describes the development of experimental tools for preparing many-particle entangled states of cold atoms in an optical cavity. We focus on the illustrative goal of preparing twin Fock states, which requires two key components: coherent photon-mediated interactions and sensitive state detection. We report the development of a phase-locked laser system that provides high power and tunability for driving interactions. Spin-exchange interactions driven by this new laser system demonstrate enhanced coherence compared with past experiments. We also report the design and characterization of avalanche photodetectors for quantum-limited detection, and we present a theoretical analysis of atomic state detection by Faraday rotation. These developments move us towards being able to generate and detect the highly entangled twin Fock state, which ultimately offers the potential for precision sensing near the fundamental Heisenberg limit.
