University of New South Wales A team of Australian engineers at the University of New South Wales (UNSW) has demonstrated a quantum bit based on the nucleus of a single atom in silicon, promising dramatic improvements for data processing in ultra-powerful quantum computers of the future. Quantum bits, or qubits, are the building blocks of quantum computers, which will offer enormous advantages for searching expansive databases, cracking modern encryption, and modelling atomic-scale...

New tech­nolo­gies that exploit quan­tum behav­ior for com­put­ing and other appli­ca­tions are closer than ever to being real­ized due to recent advances, accord­ing to a review arti­cle pub­lished this week in the jour­nal Sci­ence. These advances could enable the cre­ation of immensely pow­er­ful com­put­ers as well as other appli­ca­tions, such as highly sen­si­tive detec­tors capa­ble...

Scientists from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical rather than magnetic fields, as has been the common practice up till now. They have also been able to embed these qubits into semiconductor nanowires. The scientists' findings have been published in the...

Optical frequency combs could tame quantum bits Physicists at the University of Maryland have found a way to turn a precision measurement device into a versatile tool for manipulating quantum bits (qubits). The researchers adapted a device known as an optical frequency comb in their novel approach to performing the sorts of quantum data operations that will be vital for future quantum computers. The research appears in this week's issue of Physical Review Letters and is described in a...

Research allows control of a single electron without disturbing other nearby electrons Researchers from two National Science Foundation (NSF)-funded Materials Research Science and Engineering Centers at Princeton University and the University of California, Santa Barbara made a significant breakthrough in the worldwide pursuit of quantum computing. They engineered a method to control the spin of a single electron within a magnetic field without disturbing other nearby electrons. The method...

A major hurdle in the ambitious quest to design and construct a radically new kind of quantum computer has been finding a way to manipulate the single electrons that very likely will constitute the new machines' processing components or "qubits." Princeton University's Jason Petta has discovered how to do just that -- demonstrating a method that alters the properties of a lone electron without disturbing the trillions of electrons in its immediate surroundings. The feat is essential to the...

Word of the Day
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
