    "abstract": "The modification of initially entangled light pulses passing through\ndispersive and absorbing four-port devices is studied, using recently obtained\nresults on quantum state transformations [Phys. Rev. A 59, 4716 (1999)]. The\nfidelity and indices of quantum correlations based on the von Neumann entropy\nare calculated. Their dependence on both the pulse shape and the four-port\ndevice parameters is studied. It is shown, that due to dispersion and\nabsorption the quantum correlations are reduced substantially for large initial\nentanglement.",
