Scientific definitions for quantum bit

quantum bit

The smallest unit of information in a quantum computer. Unlike bits in classical systems, which are in one of two possible states labelled 1 and 0, a quantum bit exists in a superposition of these two states, settling on one or the other only when a measurement of the state is made. Also called qubit
