Visible-light photon counter
VLPC stands for visible-light photon counter and refers to a high quantum efficiency multi-photon counting detector which operates at visible wavelengths. The capability to count the exact number of photons that are detected is extremely important for QKD. The device has been used extensively in the central tracking detector of the D0 experiment, and for muon cooling studies for a muon collider (MICE).
