Absolute Calibration of Analog Detectors by using Parametric Down Conversion
Giorgio Brida, Maria Chekhova, Marco Genovese +3
In this paper we report our systematic study of a promising absolute calibration technique of analog photo-detectors, based on the properties of parametric down conversion. Our for…
High-Visibility Multi-Photon Interference of Classical Light
I. N. Agafonov, M. V. Chekhova, T. Sh. Iskhakov +1
It is shown that the visibility of multi-photon interference for classical sources grows rapidly with the order of interference. For three-photon and four-photon interference of tw…
Entanglement generation via phase-matched processes: different Bell states within the linewidth
G. Brida, M. V. Chekhova, M. Genovese +1
It is shown, theoretically and experimentally, that at any type-II spontaneous parametric down-conversion (SPDC) phase matching, the decoherence-free singlet Bell state is always p…
Quantum reconstruction of an intense polarization squeezed optical state
Ch. Marquardt, J. Heersink, R. Dong +5
We perform a reconstruction of the polarization sector of the density matrix of an intense polarization squeezed beam starting from a complete set of Stokes measurements. By using…
Absolute Quantum Efficiency Measurements by Means of Conditioned Polarization Rotation
Giorgio Brida, Maria Chekhova, Marco Genovese +3
We propose a new scheme for measuring the quantum efficiency of photon counting detectors by using correlated pho-tons. The measurement technique is based on a 90 rotation of the p…
Operationalistic Orthogonality Condition for Single-Mode Biphotons (Qutrits)
A. A. Zhukov, G. A. Maslennikov, M. V. Chekhova
An arbitrary polarization state of a single-mode biphoton is considered. The operationalistic criterion is formulated for the orthogonality og these states. It can be used to separ…
