Quantum computers are considered a revolution in the way the computing will be performed in the next decade or so.  Unlike the classical computers which works on the fundamentals of 0  and 1 bits or states, quantum computer works on the basic computational unit of Qubit. Classical computers store information in a string of 0 and 1’s , however Qubit before it is measured can stay in the state of 0 and 1 at the same time. This phenomenon is also called Superposition.
