Definition

The fundamental unit of information in a quantum computer, analogous to a classical computer bit, which uses quantum states to perform complex calculations.

Etymology

The word is a portmanteau of 'quantum' and 'bit' (binary digit). It was coined by physicist Benjamin Schumacher in 1995 to describe the basic unit of quantum information.
