1. Quantum Computing

1 History and Basis of Quantum Computing

Idea and concept of quantum computing was introduced way backs in 1970s and 1980s, by Richard Feynmann, David Deutsch and Paul Benioff. First breakthrough of the concept was reported in 1994 in Peter Shor’s factoring algorithm, followed by Lov Grover, searching algorithm in 1996. Isaac L. Chuang, developed the world’s first 2-qubit, 3-qubit, 5-qubit and 7-qubit quantum computer in 1996–2000. In...

Doc. Math. J. Dmv 1 Quantum Computing

The Church-Turing thesis says that a digital computer is a universal computational device; that is, it is able to simulate any physically realizable computational device. It has generally been believed that this simulation can be made eecient so that it entails at most a polynomial increase in computation time. This may not be true if quantum mechanics is taken into consideration. A quantum com...

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...
