State reconstruction of a multimode twin beam using photodetection
Jan Perina, Ondrej Haderka, Vaclav Michalek +1
Robust and reliable method for reconstructing quasi-distributions of integrated intensities of twin beams generated in spontaneous parametric down-conversion and entangled in photo…
Absolute detector calibration using twin beams
Jan Perina, Ondrej Haderka, Vaclav Michalek +1
A method for the determination of absolute quantum detection efficiency is suggested based on the measurement of photocount statistics of twin beams. The measured histograms of joi…
Photon-number distributions of twin beams generated in spontaneous parametric down-conversion and measured by an intensified CCD camera
Jan Perina, Ondrej Haderka, Martin Hamar +1
The measurement of photon-number statistics of fields composed of photon pairs, generated in spontaneous parametric down-conversion and detected by an intensified CCD camera is des…
Transverse coherence of photon pairs generated in spontaneous parametric down-conversion
Martin Hamar, Jan Perina, Ondrej Haderka +1
Coherence properties of the down-converted beams generated in spontaneous parametric down-conversion are investigated in detail using an iCCD camera. Experimental results are compa…
Angular uncertainty of momentum correlations in parametric fluorescence
Martin Hamar, Jan Perina, Vaclav Michalek +1
Uncertainty in the determination of emission angles of signal and idler photons is investigated. The role of divergence of the pump beam, width of the pump spectrum, and size of th…
Simple direct measurement of nonclassical joint signal-idler photon-number statistics and correlation area of twin photon beams
Ondrej Haderka, Jan Perina, Martin Hamar
The measurement of joint signal-idler photon-number distribution of a field obtained from spontaneous parametric downconversion using an intensified CCD camera is presented. It is…
