Definition of photon in English: photonnoun ˈfəʊtɒnˈfoʊtɑn Physics A particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. Example sentencesExamples - The team has also made progress in using photons to carry quantum information between calcium qubits.
- A photon has zero rest mass, but it carries energy and momentum.
- Until now, physicists have only been able to entangle photons, electrons and atoms, using different methods in each case.
- The world of the realist is populated by electrons and photons, quarks and gluons.
- Tiny particles such as photons or atoms can readily be put into a quantum superposition existing in two different states or places at once.
Derivatives adjective Physics Along with Tapp, he is also developing a scanner for measuring body composition that combines induction tomography with an optical imaging technique called photonic scanning. Example sentencesExamples - At the heart of this approach are the photonic wavepackets that exhibit well-defined photon number and modal character.
- In photonic technology, or photonics, the use of electrons moving through semiconductors as information carriers is replaced with the movement of light waves, as measured in units of energy called photons.
- Laser or photonic engines, because they might be propelled by laser beams inflating a gigantic sail, may have even larger specific impulses.
- Such band gaps are the photonic analogue of the electronic band gaps displayed by conventional crystals, but here they prevent photons - rather than electrons - from propagating.
