pho·ton

 (fō′tŏn′)
n.
The elementary particle of light and other electromagnetic radiation; the quantum of electromagnetic energy. The photon is the massless, neutral vector boson that mediates electromagnetic interactions.

pho·ton′ic adj.

photon

(ˈfəʊtɒn)
n
(Atomic Physics) a quantum of electromagnetic radiation, regarded as a particle with zero rest mass and charge, unit spin, and energy equal to the product of the frequency of the radiation and the Planck constant

pho•ton

(ˈfoʊ tɒn)

n.
a quantum of electromagnetic radiation, usu. considered as an elementary particle that is its own antiparticle and that has zero rest mass and charge and a spin of one.
[1926; < Greek phōt- (see phot) + -on1]
pho•ton′ic, adj.

pho·ton

(fō′tŏn′)
The smallest unit of light or other electromagnetic energy, having no mass and no electric charge. Photons behave both as particles and waves. See Note at electromagnetic radiation.

photon

A unit or quantum of electromagnetic radiation.

One is the high probability of generating unwanted multiple photons from a single-photon emitter.
The challenge is finding other light properties that can also be entangled, which would enable each photon to transmit more quantum information over large distances.
For this reason, it is hard for a physicist to imagine how the 1 energy unit from the cell tower photon can matter.
Gerhard Rempe at the Max-Planck-Institute of Quantum Optics has now for the first time realized a device which leaves the photon untouched upon detection.
The first batch of 515 kW of modules has been shipped to PHOTON Power AG.
When the low-energy photons at the centre of the cavity reached a density of about a trillion photons per cubic centimetre, they began to act as a single photon, shifting in appearance from a blurry glow to a bright point.
In Ekert-style encryption, a laser device creates pairs of entangled photons and sends (along the fiber-optic cable) one photon from each entangled pair to Alice and the other one to Bob.
The Afshar experiment is one in which it is claimed one can both determine both which path a photon has followed and that the photon self interfered in one and same experiment, violating Bohr's complementarity principle, that complementary aspects of a system cannot simultaneously be measured.
v], and k denote the four-momentum of the neutron, proton, electron, anti-neutrino, and photon, respectively--we denote the photon energy by [omega].
This switch allows a photon -- the smallest unit of light -- to influence the flow of other photons in the same way that transistors inside a PC control the flow of electrons," says Aephraim Steinberg, physics professor and co-author of a paper published in Physical Review Letters last fall.
Observing a photon directly can destroy such information, making it impossible to simply measure it and communicate the information by ordinary channels.
Solar Annual 2009: Total Eclipse also includes PHOTON Consulting's acclaimed five-year sector forecasts, based on PHOTON's screen of more than 1,500 key and emerging companies and a detailed review of the global PV supply chain, including company-by-company and market-by-market data and analysis of production, prices, costs, profit margins and installation volumes.
