  In this tutorial paper, we provide an introduction to the briskly expanding
research field of Majorana fermions in topological superconductors. We discuss
several aspects of topological superconductivity and the advantages it brings
to quantum computing. Mathematical derivation of the Kitaev model and BdG
Hamiltonian is carried out to explain the phenomena of superconductivity and
Majorana fermions. The Majorana fermions and the Non-Abelian statistics are
described in detail along with their significance for quantum engineers. The
theory provided led towards the engineering of the topological qubits using
Majoranas.
