'Quantum leap'Quantum leap spiked in lookups last week,

after K-pop group X1 announced this as the name of their forthcoming debut album.

The word is synonymous with quantum jump,

and both words have scientific and generalmeanings.

The scientific sense of quantum leap came into English in the early 20th century, meaning“an abrupt transition (as of an electron, an atom, or a molecule)

from one discrete energy state to another.”

The broadened meaning

(“an abrupt change, sudden increase, or dramatic advance”)

appears to date from the 1950s.

The coincidence of the vibration numbers calculated on the quantum and on the classical theory, respectively, for high quantum numbers and relatively small quantum leaps is perfect from the formal aspect. — Arnold Sommerfeld (trans. by Henry L. Brose), Atomic structure and spectral lines, 1923

The past forty years have witnessed what has been described as a “quantum leap” in the development of the means of mass communication — Robert Strunsky, The American Scholar, Summer 1956

Quantum leap

The thing about quantum leaps is that

they mark an abrupt change from one state to a distinctly different one,

with no in-between transitional states being possible;

but they are not large.

In fact, in physics a quantum leapis one of the smallest sorts of changes worth talking about.

Leave “quantum leap” to the subatomic physicists unless you know what you’re talking about.
