quantum leap

A sudden, spectacular advance. The term comes from nuclear physics, where a quantum leap is an abrupt transition from one energy state to another within the submicroscopic atom. William Safire pointed out that while scientists emphasize the suddenness and discontinuity of such a change, the figurative term emphasizes the size of the advance. The term was used in physics from about 1950 and began to be transferred (at first in the form of quantum jump) to other events about 1955.
