- n. The quantum of electromagnetic energy, regarded as a discrete particle having zero mass, no electric charge, and an indefinitely long lifetime. See Table at subatomic particle.
- n. A unit of retinal illumination, equal to the amount of light that reaches the retina through 1 square millimeter of pupil area from a surface having a brightness of 1 candela per square meter.
Wiktionary

Examples
“The measurement of the twin photon is intentionally delayed (8 nanoseconds) after the measurement of the signal photon.”
“Optimum antennae shape for both absorption and emission of a photon is a dipole FM antennae where the 2 opposing leads are set at the halfwave of desired cutoff.”
“Every detection of a photon is a measurement, resulting in the photon being observed just there.”
“For example, if you illuminate a surface that contains two narrow slits, each photon from the source takes both paths available to it and goes simultaneously through both slits.”
“Perhaps it was intentional to make the aliens a bit developmentally challenged, but every time an alien with a friggin 'photon cannon stared in stupefied confusion at the humans hurling rocks and arrows at them rather than blasting them into oblivion, I had to roll my eyes.”
“However, the long-distance teleportation of a photon is only a small step towards developing applications for the procedure.”
“What could it mean that a photon is in two places (or all places) at once, unless you choose to look for it, in which case it will be in just that one place that you looked?”
The Huffington Post: Charles Yu: The Science Fictional Universe
“Which detector is used to measure the twin photon is left up to quantum chance.”
“The twin photon has the same which-slot information that the signal photon would have.”
“In this experiment, a single photon is aimed at the double-slit.”
