  • Quantum atom-light interfaces in the Gaussian description for spin-1 systems 

    Colangelo, Giorgio; Sewell, Robert J.; Behbood, Naeimeh; Ciurana, Ferran Martin; Triginer Cahelles, Joaquim; Mitchell, Morgan W. (2013-10)
    Open Access
    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 ...
  • Quantum measurements with cold atomic ensembles 

    Colangelo, Giorgio (Universitat Politècnica de Catalunya, 2016-12-16)
    Doctoral thesis
    Open Access
    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 ...
