    "abstract": "We report an experimental study of group-velocity dispersion effect on an\nentangled two-photon wavepacket, generated via spontaneous parametric\ndown-conversion and propagating through a dispersive medium. Even in the case\nof using CW laser beam for pump, the biphoton wavepacket and the second-order\ncorrelation function spread significantly. The study and understanding of this\nphenomenon is of great importance for quantum information applications, such as\nquantum communication and distant clock synchronization.",
