World’s Smallest Diamond Ring: Small Is Beautiful - Gizmo Watch


World’s Smallest Diamond Ring: Small Is Beautiful - Gizmo Watch: "All beautiful things come in small packages. Attesting this saying, the scientists at the University of Melbourne in Australia have fashioned world’s smallest diamond ring. They put up their admirable creation on show at the March meeting of the American Physical Society in New Orleans. Being the smallest ever diamond ring, it measures up to a surprising 5 microns only (or millionths of a meter) in diameter and is 300 nanometers (or billionths of a meter) in thickness. The tiny ring is made by carving out a circular structure in an artificially made diamond.
Moreover, the scientists developing quantum information processing are going to be extremely benefited by the ring. The scientists illustrate the ring being a component in a device for producing and detecting single photons (particles of light) that come out of an infinitesimal impurity region inside the diamond carry information. As in common digital computers, information is stocked up in bits having a value of either “1″ or “0″ (just as a light switch can only be “on” or “off”), similarly, these photons, called cubits, can hold a value of 1 and 0 at the same time. The order of 1’s and 0’s signifies a definite quantity of information. So, the smallest diamond ring in the world may become the medium for the greater discoveries.
