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...

Quantum Computing

The main features of quantum computing are described in the framework of spin resonance methods. Stress is put on the fact that quantum computing is in itself nothing but a re-interpretation (fruitful indeed) of well-known concepts. The role of the two basic operations, one-spin rotation and controlledNOT gates, is analyzed, and some exercises are proposed.
