      We extend the covariance matrix description of atom–light quantum interfaces, originally developed for real and effective spin-1/2 atoms, to include ‘spin alignment’ degrees of freedom. This allows accurate modelling ...

      This thesis describes quantum measurements of an ensemble of cold rubidium-87 atoms. We extend the covariance matrix formalism to spin-1 systems, including effects of decoherence, losses due to probing and atom number ...
