The fundamental unit of quantum computing is qubit or quantum bit, the smallest unit of data which uses the theory of superposition from quantum physics. Superposition allows an entity to simultaneously be in multiple states. Present-day computers operate on the principle of binary bits of 0 and 1, i.e., the smallest unit of data can be represented only in these two states. On the other hand, a qubit can be a superposition of both 0 and 1, which means that the data can be represented in multiple states, increasing the computing ability of a machine.
