quantum defect kâst-e kuântomi Fr.: défaut quantique Of an atomic energy level, the difference between the principal quantum number and the effective quantum number. |

quantum efficiency kârâi-ye kuântomi Fr.: efficacité quantique In a detector, the ratio of the number of photoelectrons released to the number of incident photons at a specific wavelength. → |

quantum electrodynamics (QED) barqâtavânik-e kuântomi Fr.: électrodynamique quantique The → → |

quantum entanglement ham-gureš-e kuântomi, ham-pici-ye ~ Fr.: emmêlement quantique, intrication ~ A quantum → → |

quantum field theory negare-ye kuântomi-ye meydân Fr.: théorie quantique des champs The quantum mechanical theory based on the assumption that
the interactions between particles and fields are mediated by
messenger particles. Accordingly, particles are

quantum fluctuation oftâxiz-e kuântomi Fr.: fluctuation quantique The temporary variation in a → → |

quantum gravity gerâni-ye kuântomi Fr.: gravité quantique A theory of gravity, yet to be developed, that would properly include quantum mechanics. Because of the tensor nature of general relativity, it is not renormalizable as a field theory in perturbation from flat space. So far various attempts to quantize general relativity have been unsuccessful. |

quantum information azdâyeš-e kuântomi Fr.: information quantique The science concerned with the transmission, storage, and processing of
information using quantum mechanical systems. It exploits
the notion of → → |

quantum jump jaheš-e kuântomi Fr.: saut quantique The transition of a quantum system from one stationary state to another, accompanied by absorption or emission of energy. |

quantum mechanical system râžmân-e kuântom mekâniki Fr.: système mécanique quantique A → → |

quantum mechanics kuântom mekânik, mekânik-e kuântomi Fr.: mécanique quantique A development of Newtonian mechanics based on the discrete character of energy (Planck 1900) and the wave motion of material particles (de Broglie 1924). It is relies on the consideration that energy state of a quantum mechanical system can be derived at a given instant by a function whose square of the modulus gives the probability distribution of the coordinates of the system. Quantum mechanics is essential for the treatment of all atomic processes. It holds also for ordinary large scale processes although in this case the deviations from Newtonian mechanics are negligible. |

quantum noise nufe-ye kuântomi Fr.: bruit quantique A random variation of signal due to fluctuations in the average rate of incidence
of quanta on a detector. Quantum noise is described by the
→ |

quantum number adad-e kuântomi (#) Fr.: nombre quantique A number used in quantum mechanics, specifying the state of an electron bound in an atomic system. The quantum numbers are integers or half integers and specify the number of units of energy, momentum, spin, etc. possessed by an electron. |

quantum of action kuântom-e žireš Fr.: quantum d'action Since → |

quantum phase transition (QPT) gozareš-e fâz-e kuântomi Fr.: transition de phase quantique A phase transitions that occurs at zero temperature as a function of a
non-thermal parameter like → → |

quantum state estât-e kuântomi Fr.: état quantique In → |

quantum theory negare-ye kuântomi (#) Fr.: théorie quantique The theoretical basis of modern physics which describes the behavior and
interactions of elementary particles or energy states based on the assumptions
that energy is subdivided into discrete amounts and that matter possesses wave
properties. → |

quantum unitarity yekâyigi-ye kuântomi Fr.: unitarité quantique A property in → |

quantum walk puyeš-e kuântomi Fr.: marche quantique A generalization of the classical concept of → → |

quantum yield bâzdeh-e kuântomi Fr.: rendement quantique In photochemistry, the number of defined events which occur per photon absorbed by the system. |
