Optimal Quantum Phase Estimation
U. Dorner, R. Demkowicz-Dobrzanski, B. J. Smith +4
By using a systematic optimization approach we determine quantum states of light with definite photon number leading to the best possible precision in optical two mode interferomet…
Statistics of multiphoton events in spontaneous parametric down-conversion
Wojciech Wasilewski, Czeslaw Radzewicz, Robert Frankowski +1
We present an experimental characterization of the statistics of multiple photon pairs produced by spontaneous parametric down-conversion realized in a nonlinear medium pumped by h…
Quantifying the non-Gaussian character of a quantum state by quantum relative entropy
Marco G. Genoni, Matteo G. A. Paris, Konrad Banaszek
We introduce a novel measure to quantify the non-Gaussian character of a quantum state: the quantum relative entropy between the state under examination and a reference Gaussian st…
