Energy can neither be created nor be destroyed but it can be conserved. The processors of present day computers are designed using conventional logic circuits which are irreversible in nature. They suffer from loss of information during computation, leading to energy dissipation in the form of heat affecting the performance and life of the circuits. These limitations of conventional logic circuits can be overcome by the reversible logic circuits designed using quantum gates, the essential elements for quantum computing. Quantum computing is an emerging area of research which finds application in optical computing, DNA computing, cryptography, low power CMOS design, digital signal processing and nanotechnology.
