Definition that contains quantum theory
- quantum a discrete amount of something that is analogous to the quantities in quantum theory
- quantum (physics) the smallest discrete quantity of some physical property that a system can possess (according to quantum theory)
- planck German physicist whose explanation of blackbody radiation in the context of quantized energy emissions initiated quantum theory (1858-1947)
- qed a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
- uncertainty principle (quantum theory) the theory that it is impossible to measure both energy and time (or position and momentum) completely accurately at the same time

- quantisation the act of dividing into quanta or expressing in terms of quantum theory
- quantum electrodynamics a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
- wave mechanics the modern form of quantum theory; an extension of quantum mechanics based on Schrodinger's equation; atomic events are explained as interactions between particle waves
