Conventional computers store information in the form of bits and bytes and the scope is only limited to 0s and 1s, thus flexibility in conventional computers is restrained. On the other hand, Quantum computers use a totally different form of data storage called "Qubits". Qubits are not only restrained to values such as 0 and 1, in fact they also provide a possibility of the information being intermediate (Superposition) between 0 and 1. For better understanding about the qubits, these are various but stable energy levels of the sub-atomic particles or photons in three-dimensional space. Each sub-atomic particle in the collection of qubits can be used to represent a variety of information or data.
