quantum theory The area of physics concerned with the behaviour of particles at small scales where the discrete nature of matter becomes important and more generally with other quantum phenomena such as quantum information and quantum computers. The results of experiments early in the 20th century could only be explained by quantities such as momentum and energy only being able to take certain discrete values, yet the behaviour of particles taken together was that of a wave, giving rise to the wave-particle duality. See also Heisenberg's uncertainty principle, measurement, observable, Schrödinger's equation.
