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...

Newly fabricated devices are a step toward quantum computing Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers. The device is described in the American Institute of Physics' journal Applied Physics Letters. Photodetectors based on single quantum dots are expected to find uses in optoelectrical...

Natelson Lab pioneers technique to measure heat, dissipation at very small scales You can touch a functioning light bulb and know right away that it's hot. Ouch! But you can't touch a single molecule and get the same feedback. Rice University researchers say they have the next best thing -- a way to determine the temperature of a molecule or flowing electrons by using Raman spectroscopy combined with an optical antenna. A new paper from the lab of Douglas Natelson, a Rice professor of physics...

Given their outstanding mechanical and electrical properties, carbon nanotubes are attractive building blocks for next-generation nanoelectromechanical devices, including high-performance sensors, logic devices, and memory elements.  However, manufacturing challenges associated with creating well-ordered arrays of individual carbon nanotubes and the nanotube-devices' prevalent failure modes have prevented any large-scale commercial use. Now, researchers at Northwestern University, the...

Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a new class of computers and electronics that are faster and consume less power than today's. The semiconducting nanostructures might be used to revolutionize electronics by replacing conventional silicon components and circuits. However, one obstacle in their application is that metallic versions form unavoidably during the...

Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
