Washington, March 15: Australian experts have created the world's smallest diamond ring which is 300 nanometres in thickness, and five microns in diameter. University of Melbourne scientists have revealed that they made the tiny ring by carving out a circular structure in an artificially made diamond.

The ring may be helpful for scientists who are developing quantum information processing, say its makers. The scientists describe their ring as a component in a device for producing and detecting single photons (particles of light), which can carry information. An ordinary digital computer stores information in bits that have a value of either "1" or "0", just as a light switch can only be "on" or "off". The order of 1's and 0's indicates a certain piece of information.

The researchers say that the fact that photons can hold a value of 1 and 0 at the same time suggests that they may expand the possibility of information storage, reports Live Science.

The development of the tiny diamond ring was announced at the March meeting of the American Physical Society in New Orleans.
