How to use quantum bit in a sentence
Instead of the traditional bits made of 1s and 0s, they use quantum bits that can represent different values at the same time.

Scientific definitions for 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
