Latest Quantum computer Stories
Physicists demonstrate means for quantum bits to communicate over long distances.
A quantum particle is hard to grasp, because one cannot determine all its properties precisely at the same time.
A research group led by computer scientists at the UCLA Henry Samueli School of Engineering and Applied Science has proved that cryptography â€” the practice and study of hiding information â€” that is based solely on physical location is possible by using quantum mechanics.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated an ion trap with a built-in optical fiber that collects light emitted by single ions (electrically charged atoms), allowing quantum information stored in the ions to be measured.
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.
