    Objective approach to biased tomography schemes

  • Original language description

    The intrinsic relationship between the maximum-likelihood quantum-state estimation and the representation of the signal is elaborated. A quantum analogy of the transfer function determines the space where a successful reconstruction can be achieved. Thisprovides a tool for reducing the number of dimensions of the observed system based on physical characteristics of the reconstruction scheme rather than some ad hoc truncations. The method is illustrated with two examples of practical importance: an optical quantum homodyne tomography and a simple and robust tomography of an optical signal recorded by realistic binary detectors.

  • Czech description

    Zkoumáme vztah mezi rekonstrukcí kvantového stavu metodou maximální věrohodnosti a reprezentací měřeného signálu. Je nalezena kvantová analogie přenosové funkce, která omezuje množinu hledaných parametrů. Metoda je ilustrována na dvou prakticky důležitých inverzních ůlohách: optické homodynní tomografii a tomografii optického signálu detekovaného nedokonalými binárními detektory.
