With careful engineering, it\u2019s possible to turn electrons\u2019 quantum behavior into an advantage.<\/p>\n<p>A team of English, Canadian, and Italian researchers have developed a single-molecule <a href=\"https:\/\/spectrum.ieee.org\/tag\/transistor\" class=\"\">transistor<\/a> that harnesses quantum effects. At low temperatures, the single-molecule device shows a strong change in current with only a small change in gate voltage, nearing a physical limit known as the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Subthreshold_slope\" target=\"_blank\" class=\"\">sub-threshhold swing<\/a>. Getting near or beyond this limit will allow transistors to be switched with lower voltages, making them more efficient and generating less waste heat. The research team, including physicists at Queen Mary University of London, achieved this by taking advantage of how quantum interference alters the flow of current in single molecules.<\/p>\n<p>\u201cWe\u2019ve demonstrated, in principle, that you can use destructive quantum interference for something useful.\u201d <strong>\u2014Jan Mol, Queen Mary University of London<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As transistors are made ever tinier to fit more computing power into a smaller footprint, they bump up against a big problem: quantum mechanics.
