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:
“Nine-tenths of English poetic literature is the result either of vulgar careerism or of a poet trying to keep his hand in. Most poets are dead by their late twenties.”
—Robert Graves (1895–1985)
“From time to time there appear on the face of the earth men of rare and consummate excellence, who dazzle us by their virtue, and whose outstanding qualities shed a stupendous light. Like those extraordinary stars of whose origins we are ignorant, and of whose fate, once they have vanished, we know even less, such men have neither forebears nor descendants: they are the whole of their race.”
—Jean De La Bruyère (1645–1696)
