Scientists Record Electron's Quantum Behavior
2014-08-18 03:07:24

By Jane Marie Andrew, University of Chicago A University of Chicago-led team of researchers has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique uses ultrafast pulses of laser light, both to control the defect’s entire quantum state and observe how that single electron state changes over time. The work appears in this week’s online Science Express and will be published in print...

A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers from the US. Presenting the device today, 8 February, in the Institute of Physics and German Physical Society's New Journal of Physics, it has been described as the "building block of future quantum networks." In an optical quantum network, information is carried between points by photons — the basic unit of light. There is a huge potential for this...

Diamond, nature's hardest known substance, is essential for our modern mechanical world — drills, cutters, and grinding wheels exploit the durability of diamonds to power a variety of industries. But diamonds have properties that may also make them excellent materials to enable the next generation of solid-state quantum computers and electrical and magnetic sensors. To further explore diamonds' quantum computing potential, researchers from the University of Science and Technology of...

Physicists working at the University of California, Santa Barbara and the University of Konstanz in Germany have developed a breakthrough in the use of diamond in quantum physics, marking an important step toward quantum computing. The results are reported in this week's online edition of Nature Physics. The physicists were able to coax the fragile quantum information contained within a single electron in diamond to move into an adjacent single nitrogen nucleus, and then back again using...

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. Their new research is published in the online edition of the Proceedings of the National Academy of Sciences (PNAS), and will soon be published in the print edition of the journal. The findings may enable new applications for semiconductors...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
