    "abstract": "We report a procedure to detect mid-infrared single photons at 4.65 um via a\ntwo-stage scheme based on Sum Frequency Generation, using a Periodically Poled\nLithium Niobate (PPLN) nonlinear crystal and a Silicon Avalanche Photodiode. An\nexperimental investigation shows that, in addition to a high timing resolution,\nthis technique yields a detection sensitivity of 1.24 pW with 63mW of net pump\npower.",
