What is the basic unit of information used to encode data in quantum computing?

Qubit

A qubit, or quantum bit, is the quantum version of the classical binary bit used in traditional computing. Unlike a standard bit that must be either 0 or 1, a qubit can exist in a state of superposition, allowing it to represent multiple states simultaneously. This unique property enables quantum computers to process vast amounts of data and solve complex problems much faster than today's most powerful supercomputers.
