Glimpses of Quantum Computation

Quantum computation is a promising field of study because the conventional computer hardware is fast reaching its limit of computational power. A further advancement can be achieved only by a completely different set of physical properties and operations. This paper presents a brief overview of the fundamental concepts of quantum computation. The concept of a quantum bit, in contrast with the classical bit, is explained. The quantum logic gates ana quantum circuits are described along with appropiate examples. Quantum parallelism, a phenomenon that is at the ischolar_main of the power of quantum computation, is explained briefly.
