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…

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…
