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…
