(quantum mechanics) Any of several quantum mechanical effects in which a particle disobeys the laws of classical mechanics.

(informal) The quark-gluon plasma which existed in the first millionth of a second of the universe.

(quantum mechanics) The discontinuous change of the state of an electron in an atom or molecule from one energy level to another. / (figuratively) An abrupt, extreme change.

(physics) The branch of physics which studies matter and energy at the level of atoms and other elementary particles, and substitutes probabilistic mechanisms in place of classical Newtonian ones.

(physics) A branch of theoretical physics aiming to unite quantum mechanics with general relativity. / (quantum mechanics) The gravitational force modeled as a quantum field.

(quantum mechanics) Any of the possible states of a quantum mechanical system.

(quantum mechanics) One of certain integers or half-integers that specify the state of a quantum mechanical system (such as an electron in an atom).

(quantum mechanics) the instantaneous transference of a quantum state to a distant location using quantum entanglement and the transmission of classical information

(quantum mechanics) A quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects are spatially separated.

(law) an inference that the defendant has promised to pay the plaintiff for the plaintiff's work or labor as much as he should deserve
