Recently, Australian scientists disclosed the world's smallest electronic switch with only a few atoms. This electronic switch will reduce the size of the micro-chip and bring revolutionary changes to the calculation speed. This 7-atom-sized transistor, which measures four billionths of a meter in size and is embedded in a single silicon crystal, is the first step toward "quantum computing." Quantum calculation will make the calculation speed 100 times faster than the existing equipment. Michelle Simmons, head of the study, said the technology is important for cryptanalysis, financial transaction processing and weather forecasting, including testing a wide range of possible conditions. You will be able to use traditional computers to solve problems that need to be solved with more time than the life of the universe. The University of New South Wales Quantum Computing Center and the University of Wisconsin-Madison created the transistor by using a special microscope operating atom. This technological breakthrough promises to reduce the size of a tiny chip that contains billions of transistors by a factor of 100 while exponentially speeding up processing. Simmons said that now you can get a computer in your hand. The computer's components are 1,000 times thinner than human hair. The commercial application of this technology takes about five years. Her team is currently developing the first ultra-fast quantum computer. The size of this computer is only as big as the current chip.
