quantum leap

A dramatic advance, especially in knowledge or method, as in Establishing a central bank represents a quantum leap in this small country's development. This term originated as quantum jump in the mid-1900s in physics, where it denotes a sudden change from one energy state to another within an atom. Within a decade it was transferred to other advances, not necessarily sudden but very important ones.

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.
