Measuring Quantum Correlations with Imperfect Photoncounters - Si-Hui Tan

The recent emergence of photon-number-resolving detectors (PNRDs) makes the characterization of multiphoton states via photoncounting possible. Here I will discuss several popular types of PNRDs and show how we can model realistic PNRDs using positive-operator valued measures. I apply this model to the measurement of quantum correlations and the calibration of these PNRDs.
