    Tomography for quantum diagnostics

  • Original language description

    The quantification of relevant statistical errors is an indispensable but often neglected part of any tomographic scheme used for quantum diagnostic purposes. We introduce a novel resolution measure, which provides ?error bars? for any inferred quantityof interest. This is illustrated with an example of the diagnostics of non-classical states based on the value of the reconstructed Wigner function at the origin of the phase space. We show that such diagnostics is meaningful only when a lot of prior information on the measured quantum state is available. Our resolution measure also provides an effective tool for optimization and resolution tuning of tomography schemes

    Tomografie pro kvantovou diagnostiku

  • Czech description

    Je zavedena nová míra rozlišení, která poskytuje chybové intervaly pro libovolnou odhadovanou veličinu. Metoda je demonstrována na příkladu diagnostiky neklasických stavů s pomocí hodnoty rekonstruované Wignerovy funkce v počátku. Nově zavedené rozlišeníse ukazuje být efektivním nástrojem pro optimalizaci tomografických postupů
