    Coherent-State information concentration and purification in atomic memory

  • Original language description

    We propose a feasible method of coherent-state information concentration and purification utilizing quantum memory. The method allows us to optimally concentrate and purify information carried by many noisy copies of an unknown coherent state (randomly distributed in time) to a single copy. Thus non-classical resources and operations can be saved, if we compare information processing with many noisy copies and a single copy with concentrated and purified information.

    Koncentrace a vyčištění informace obsažené v koherentním stavu pomocí atomové paměti

  • Czech description

    Navrhujeme proveditelnou metodu pro koncentraci a vycisteni informace obsazene v koherentnim stavu vyuzivajici kvantove pameti. Tato metoda nam umoznuje optimalne koncentrovat a cistit informaci nesenou mnoha kopiemi neznameho koherentniho stavu (nahodnedistribuovanych v case) do jedne kopie. Jestlize porovname zpracovani informace vyuzivajicich mnoha zasumenych kopii a jedne kopie s koncentrovanou a vycistenou informaci, potom muzeme usetrit mnoho operaci a neklasickych zarizeni.
