The Quantum Computing Challenge

The laws of physics imposes limits on increases in computing power. Two of these limits are interconnect wires in multicomputers and thermodynamic limits to energy dissipation in conventional irreversible technology. Quantum computing is a new computational technology that promises to eliminate problems of latency and wiring associated with parallel computers and the rapidly approaching ultimat...

Quantum Computing

uantum computers will utilize nonclassical logic operations to perform numerical calculations that are not feasible on conventional computers. The enhanced capabilities of quantum computers result partly from their expected ability to perform many different calculations simultaneously on a single processor. The Applied Physics Laboratory is developing an optical approach to quantum computing. (

Quantum Computing

This paper gives a glimpse of basic quantum computing concepts, which is an active area of research in today's world. The discussion starts with difference between a quantum computer and a classical one at the bit level, register level, logic gates level and at circuit level. Then, some of the important quantum phenomena such as quantum entanglement and quantum interference are discussed. After...
