Real-time phase-reference monitoring of a quasi-optimal coherent-state receiver
Matteo Bina, Alessia Allevi, Maria Bondani +1
The Kennedy-like receiver is a quasi-optimal receiver employed in binary phase-shift-keyed communication schemes with coherent states. It is based on the interference of the two si…
Luminescence-induced noise in single photon sources based on BBO crystals
Radek Machulka, Karel Lemr, Ondřej Haderka +3
Single-photon sources based on the process of spontaneous parametric down-conversion play a key role in various applied disciplines of quantum optics. We characterize intrinsic lum…
Spatial properties of twin-beam correlations at low- to high-intensity transition
Radek Machulka, Ondrej Haderka, Jan Perina +3
It is shown that spatial correlation functions measured for correlated photon pairs at the single-photon level correspond to speckle patterns visible at high intensities. This corr…
Coherence properties of high-gain twin beams generated in pump-depletion regime
Alessia Allevi, Ottavia Jedrkiewicz, Enrico Brambilla +4
Twin-beam coherence properties are analyzed both in the spatial and spectral domains at high-gain regime including pump depletion. The increase of the size of intensity auto- and c…
Bracket states for communication protocols with coherent states
Alessia Allevi, Stefano Olivares, Maria Bondani
We present the generation and characterization of the class of bracket states, namely phase-sensitive mixtures of coherent states exhibiting symmetry properties in the phase-space…
Absolute calibration of photon-number-resolving detectors with an analog output using twin beams
Jan Perina, Ondrej Haderka, Alessia Allevi +1
A method for absolute calibration of a photon-number resolving detector producing analog signals as the output is developed using a twin beam. The method gives both analog-to-digit…
