    Conditional generation of arbitrary single-mode quantum states of light by repeated photon subtractions

  • Original language description

    We propose a scheme for the conditional generation of arbitrary finite superpositions of Fock states in a single mode of a traveling optical field. The setup requires a source of squeezed vacuum states, beam splitters, strong coherent beams, photodetectors with single-photon sensitivity, and a final squeezer. If we want to generate a squeezed superposition of Fock states, which is sufficient in several applications, then the last squeezer is not even needed. The thrust of this method is that it achievesa high fidelity without requiring photodetectors with a high efficiency or a single-photon resolution. The possibility to improve its scaling by using a quantum memory is also discussed.

    Podmíněná generace libovolného jednomodového stavu světla pomocí opakovaného odečítání fotonů

  • Czech description

    Je navrženo schéma pro podmíněnou generaci libovolných konečnýchsuperpozic Fockových stavů v jednom módu optického pole. Tato metoda jezaložena na podmíněném odečítání jednotlivých fotonů z módu pole avyžaduje pouze zdroj stlačených stavů, lineární optické elementy,jednofotonové detektory a pomocný laser.
