2.
any theory that treats certain phenomena by the methods of quantum mechanics:

noun
1.
a theory concerning the behaviour of physical systems based on Planck’s idea that they can only possess certain properties, such as energy and angular momentum, in discrete amounts (quanta). The theory later developed in several equivalent mathematical forms based on De Broglie’s theory and on the Heisenberg uncertainty principle See wave mechanics
quantum theory n.
The theory that radiant energy is transmitted in the form of discrete units.

quantum tunneling A quantum mechanical effect in which particles have a finite probability of crossing an energy barrier, such as the energy needed to break a bond with another particle, even though the particle’s energy is less than the energy barrier.
