Washington DC [US], September 22 (ANI): Engineers discovered how to make atomic nuclei 'talk' inside silicon chips, opening the door to scalable quantum computers. This breakthrough brings scalable, silicon-based quantum computing much closer to reality. They have used the nuclear spin of phosphorus atoms, implanted in a silicon chip, to encode quantum information. 'Over the last 15 years, our group has pioneered all the breakthroughs that made this technology a real contender in the quantum computing race. She adds that 20 nanometers is the scale at which modern silicon computer chips are routinely manufactured to work in personal computers and mobile phones.
