    "abstract": "The goal of this research is to determine and study a physical system that\nwill enable a fast and intrinsically two-photon detector, which would be of\ninterest for quantum information and metrology applications. We consider two\ntypes of two-photon processes that can be observed using a very faint, but\nquantum-correlated biphoton field. These are optical up-conversion and an\nexternal photoelectric effect. We estimate the correlation enhancement factor\nfor the biphoton light compared to coherent light, report and discuss the\npreliminary experimental results.",
