A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes (SPAD)," act like mini Geiger counters, producing a "tick" each time a photon is detected. The researchers present their findings in Applied Physics Letters, a journal published by the American Institute of Physics. "In the past, making these detectors required specialized processes, but recently there has been tremendous...
