Abstract: Basic concepts of quantum mechanics are used to build the ideas of quantum computation. Meaning of measurement in quantum physics, referring to quantum states and eigenstates is considered as the bases of quantum computation. Formation of qubits and the construction of multiple qubit system gives rise to entangled states. The Hadamard gate whose action on a set of qubits in their basis states is the first step in many quantum algorithms has also been discussed. Simple Boolean functions are used to do quantum computations which are as capable as classical computers. Difficulties to build algorithms for quantum computers are also highlighted.
