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 quantity of 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

  • 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 rozlišení se ukazuje být efektivním nástrojem pro optimalizaci tomografických postupů (cs)
