image: Vision of a spin-based quantum computer: an array of quantum dots is formed in an electron sheet (red) by biasing metallic gates. Every dot contains a single electron spin (arrow) representing a qubit (proposal by D. Loss and D.P. Divencenzo). This research demonstrates two-qubit operation and spin correlation by single-shot spin read-out. This image relates to an article that appeared in the Aug. 4, 2011, issue of Science Express, published by AAAS. The study, by Dr. Katja Nowack of Delft University of Technology in Delft, the Netherlands, and colleagues was titled, "Single-Shot Correlations and Two-Qubit Gate of Solid-State Spins." view more
