(quantum mechanics) The limit on measurement accuracy at quantum scales due to back-action effects. / (spectroscopy) The shortest wavelength in an X-ray spectrum.

(quantum computing) A computer that exploits quantum mechanical phenomena to transcend classical time complexity limitations.

plural of quantum computer

plural of quantum Hall effect

(physics) The quantum number that represents the angular momentum of an atomic orbital

(physics) The quantum number (of an atomic orbital) that specifies the energy of an electron in an atom and, hence, which shell it occupies

(physics) A quantum number of an atomic orbital, whose possible values are related to the azimuthal quantum number, that denotes the energy levels in a subshell.

(physics) A quantum number that specifies the spin of a particle; for an electron, it may only take the values ±1/2

Information theory adapted to deal with information held and/or handled by quantum systems, i.e., in which information is measured in qubits instead of classical bits.

(quantum mechanics) A theory of quantum fields; the result of applying second quantization to Classical Relativistic Field Theory.
