Morphology

quantum + jump

The word 'jump' clearly conveys a rapid increase, and 'quantum' (a discrete amount) suggests a distinct change, so a learner who knows both words could infer some kind of sudden or discrete change. However, the conventional idiomatic sense of a large or significant advance is a metaphorical extension from physics and not directly predictable from 'quantum' as given, so the meaning is only partially transparent to a B1 learner.

Etymology

Quantum jump is also used to mean a big, sudden improvement. People borrowed the picture of an electron's abrupt move, so quantum and jump together became a way to say 'a sudden, large improvement'.
