Smallest yet fastest computer made in Japan where else?
Scientists in Japan have developed the world’s tiniest computer, the device that is not larger than a few molecules and that is claimed to mimic how the most complicated computer – human brain works. Well that’s not all, they also go further to claim that it’s faster than most computers we know of; in fact 16 times more. The tiny computer is made of a duroquinone, a molecule looking like a hexagonal plate with four cones attached to it. Duroquinone is less than a nanometer large, which is hundreds times smaller than a wavelength of a visible light. The device is formed with 17 duroquinone molecules with one molecule positioned in the center and 16 others making up a ring. This wonder sits on a gold surface. Anirban Bandyopadhyay, an artificial intelligence and molecular electronics expert at the National Institute for Materials Science at Tsukuba in Japan, explained that the work of the device resembles the way brain cells interact.
A pulse sent to a central molecule, having four cones and linked to another 16 duroquinones will result in almost 4.3 billion different operations if compared to two different outcomes a normal computer transistor can perform.
