What is a quantum bit (qubit)?

A quantum bit, otherwise known as a qubit, is the basic unit of data in quantum computing.

Qubits are subject to phenomena known as superposition and entanglement, due to their quantum nature.

Superposition allows the qubits of a quantum computer to be in multiple states (0, 1 or both) The more qubits you have, the more calculations you can process in parallel.
