For detection systems that record discrete events, such as particle and nuclear detectors, the dead time is the time after each event during which the system is not able to record another event. An everyday life example of this is what happens when someone takes a photo using a flash - another picture cannot be taken immediately afterward because the flash needs a few seconds to recharge. In addition to lowering the detection efficiency, dead times can have other effects, such as creating possible exploits in quantum cryptography.

Famous quotes containing the words dead and/or time:
“You can never betray the people who are dead, so you go on being a public Jew; the dead can’t answer slurs, but I’m here. I would love to think that Jesus wants me for a sunbeam, but he doesn’t.”
—Anita Brookner (b. 1938)
“Mostly, we authors must repeat ourselves—that’s the truth. We have two or three great moving experiences in our lives—experiences so great and moving that it doesn’t seem at the time that anyone else has been so caught up and pounded and dazzled and astonished and beaten and broken and rescued and illuminated and rewarded and humbled in just that way ever before.”
—F. Scott Fitzgerald (1896–1940)
