means A computing approach that uses quantum physics—particles existing in multiple states at once—to process certain problems far faster than ordinary computers can.

from 'Quantum' comes from Latin quantus, 'how much,' adopted into physics in the early 20th century to describe energy arriving in discrete packets rather than smooth flows. 'Computing' traces to Latin computare, 'to reckon together.' The phrase itself is a late-20th-century coinage, emerging as physicists like Feynman and Deutsch asked whether the strange rules of quantum mechanics—superposition, entanglement—could be harnessed to compute rather than merely be observed.
