Abstract

The authors propose a new scheme for measuring the quantum efficiency of photon counting detectors by using correlated photons. The scheme consists in measuring the polarization state of one member of a correlated pair after a 90deg polarization rotation conditioned to the detection of the other correlated photon after polarization selection. The authors present experimental results obtained with this scheme compared with traditional correlated photon calibration

We propose a new scheme for measuring the quantum efficiency of a single-photon detection apparatus by using polarization-entangled states. The scheme consists of measuring the polarization of a member of a polarization-entangled pair after a 90° polarization rotation conditional on the detection of the correlated photon after polarization selection. We present experimental results obtained with this scheme compared with traditional biphoton calibration. Our results show the interesting potentiality of the suggested scheme.

Absolute Quantum Efficiency Measurements by Means of Conditioned Polarization Rotation

We propose a new scheme for measuring the quantum efficiency of photon counting detectors by using correlated photons. The measurement technique is based on a 90/spl deg/ rotation of the polarization of one photon member of a correlated pair produced by parametric down-conversion, conditioned on the detection of the other correlated photon after polarization selection. We present experimental results obtained with this scheme.

Experimental realization of a measurement conditional unitary operation at single photon level and application to detector characterization

Marco Genovese, G. Brida, Maria V. Chekhova +4 more

Our last experimental results on the realization of a measurement-conditional unitary operation at single photon level are presented. This gate operates by rotating by 90° the polarization of a photon produced by means of Type-II Parametric Down Conversion conditional to a polarization measurement on the correlated photon. We then propose a new scheme for measuring the quantum efficiency of a single photon detection apparatus by using this set-up. We present experimental results obtained with this scheme compared with traditional biphoton calibration. Our results show the interesting potentiality of the suggested scheme.

Our last experimental results on the realization of a measurement-conditional unitary operation at single photon level are presented. This gate operates by rotating by $90^o$ the polarization of a photon produced by means of Type-II Parametric Down Conversion conditional to a polarization measurement on the correlated photon. We then propose a new scheme for measuring the quantum efficiency of a single photon detection apparatus by using this set-up. We present experimental results obtained with this scheme compared with {\\it traditional} biphoton calibration. Our results show the interesting potentiality of the suggested scheme.

Measurement of quantum efficiency using correlated photon pairs and a single-detector technique

A. Czitrovszky, Alexander V. Sergienko, Peter J. Jani +1 more

A new approach is proposed to the calibration of photodetectors and the determination of the absolute value of the quantum efficiency of photon-counting photomultipliers using entangled-photon pairs. It is based on a new single-photodetector technique and a special modulation of the entangled-photon flux. The absolute values of the quantum efficiency have been determined for several photon-counting photomultipliers.
