    "abstract": "We demonstrate experimentally a new technique to control the bandwidth and\nthe type of frequency correlations (correlation, anticorrelation, and even\nuncorrelation) of entangled photons generated by spontaneous parametric\ndownconversion. The method is based on the control of the group velocities of\nthe interacting waves. This technique can be applied in any nonlinear medium\nand frequency band of interest. It is also demonstrated that this technique\nhelps enhance the quality of polarization entanglement even when femtosecond\npulses are used as a pump.",
