Latest Quantum computer Stories
Since Richard Feynman's first envisioned the quantum computer in 1982, there have been many studies of potential candidates -- computers that use quantum bits, or qubits, capable of holding an more than one value at a time and computing at speeds far beyond existing silicon-based machines for certain problems.
The remarkable ability of an electron to exist in two places at once has been controlled in the most common electronic material â€“ silicon - for the first time.
CAMBRIDGE, Mass., June 22, 2010 /PRNewswire/ -- Raytheon Company's (NYSE: RTN) BBN Technologies has achieved a major advance in quantum information technology with the coupling of light and superconductors.
Any physical system - be it an electron, a molecule of water, a virus, a human being, a whole planet â€“ is characterized at each moment in time distinctively and specifically in a specific place by particular characteristics.
For most people, frustration is a condition to be avoided - but for scientists studying certain "frustrated" ensembles of interacting components â€“ that is, those which cannot settle into a state that minimizes each interaction â€“ it may be the key to understanding a host of puzzling phenomena that affect systems from neural networks and social structures to protein folding and magnetism.
Despite a steady improvement in the speed of conventional computers during the last few decades, certain types of problems remain computationally difficult to solve.
On Monday, Australian scientists unveiled the world's smallest electronic switch measuring just a few atoms, which will shrink microchips and revolutionize computing speeds.
McGill researchers make important contribution to the development of quantum computing.
A team of scientists at UC Santa Barbara that helped pioneer research into the quantum properties of a small defect found in diamonds has now used cutting-edge computational techniques to produce a road map for studying defects in alternative materials.
Scientists at the National Institute of Standards and Technology (NIST) have developed the first "dimmer switch" for a superconducting circuit linking a quantum bit (qubit) and a quantum busâ€”promising technologies for storing and transporting information in future quantum computers.
