What is Qubit?

In quantum computing, a qubit or quantum bit is the basic unit of quantum information—the quantum version of the classical binary bit physically realized with a two-state device. A qubit is a two-state quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics

The graph below shows what is the difference between a classical bit and a Quantum Bit as a classical bit has only 1's and 0's but a qubit is somehow different.
