Latest Quantum computer Stories
Ever since audiences heard Goldfinger utter the famous line, â€œNo, Mr. Bond; I expect you to die,â€ as a laser beam inched its way toward James Bond and threatened to cut him in half, lasers have been thought of as white-hot beams of intensely focused energy capable of burning through anything in their path.
An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers.
The PhD thesis by Carlos EcheverrÃa Arrondo, Doctor in Physics from the Public University of Navarre and entitled â€œOn doped semiconductor quantum dots and magnetic nanowiresâ€, studied the behaviour and properties of nanometric-scale semiconductor crystals.
Dr. David Awschalom, professor of physics at the University of California, Santa Barbara has been selected as the recipient of the 2010 Materials Research Society Turnbull award for research funded in large measure by the Air Force Office of Scientific Research.
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.
- The deadly nightshade, Atropa Belladonna, which possesses stupefying or poisonous properties.
- A sleeping-potion; a soporific.
- To mutter deliriously.
