Suppression of tensor decoherence in QND measurements of atomic ensembles
Abstract/Contents
- Abstract
- Atomic ensembles have assumed a central role in modern high precision sensing applications including atomic clocks, magnetometers, gravimeters, and accelerometers. In the past decade significant advances have been made pushing these sensors to, and in some cases beyond the standard quantum limit of sensitivity. Much recent interest has been in the use of Quantum Non-Demolition (QND) measurements to perform state-preparation and metrology simultaneously. QND measurements are typically accomplished through interaction with an off-resonant optical probe. I present techniques to recreate QND measurements in the case that the Probe-Atom interaction is non-QND due to the presence of a tensor light-shift Hamiltonian. The tensor interaction naturally arises in detuned systems with spin one or higher and leads to a series of effects, including Hamiltonian evolution, technical noise enhancement, inhomogeneous and homogeneous dephasing that reduce measurement accuracy in these systems. I demonstrate several techniques for active cancellation of the tensor Hamiltonian and show compatibility with QND measurement and sub-shotnoise metrology performance.
