    Realization of a minimal disturbance quantum measurement

  • Original language description

    We report the first experimental realization of an "optimal" quantum device able to perform a minimal disturbance measurement on polarization encoded qubits saturating the theoretical boundary established between the classical knowledge acquired of any input state, i.e., a "classical guess," and the fidelity of the same state after disturbance due to measurement. The device has been physically realized by means of a linear optical qubit manipulation, postselection measurement, and a classical feed-forward process.

    Realizace kvantového měření s minimální poruchou

  • Czech description

    Je popsána první experimentální realizace optimálního kvantového měření na polarizačním stavu fotonu saturující teoretickou nerovnost mezi fidelitu měření a fidelitou porušeného stavu. Měření je realizováno pomocí lineární optiky, jedno-fotonové detekcea klasického elektro-optické opravy.
