Abstract

Fast characterization of pulsed spontaneous parametric down conversion (SPDC) sources is important for applications in quantum information processing and communications. We propose a simple method to perform this task, which only requires measuring the counts on the two output channels and the coincidences between them, as well as modeling the filter used to reduce the source bandwidth. The proposed method is experimentally tested and used for a complete evaluation of SPDC sources (pair emission probability, total losses, and fidelity) of various bandwidths. This method can find applications in the setting up of SPDC sources and in the continuous verification of the quality of quantum communication links.

Principle of the evaluation of I2 for the simple case of a rectangular filter function. The shaded area is proportional to the effective value of I2. When the filter is centered at the degeneracy frequency (zero detuning), I2 is maximum (a). When detuning is non-zero, I2 is reduced : some photons within the filter bandwidth have their twins transmitted (b), while this is not the case for others (c).

Comparison of the theoretical and experimental transmission (a) and normalized value of I2 (b) plotted as a function of frequency detuning with respect to the filter center frequency νF, for two different filtering devices: a DWDM filter {4} and a DWDM filter plus a FP etalon {5}.
