Did Physicists Open a Portal to Extra Time Dimension, As Claimed?

That’s the way the story reads at Scientific American. But experimental physicist Rob Sheldon says not so fast…

At Scientific American, we were told last month: “Physicists have devised a mind-bending error-correction technique that could dramatically boost the performance of quantum computers”: “It is very exciting to see this unusual phase of matter realized in an actual experiment, especially because the mathematical description is based on a theoretical ‘extra’ time dimension,” says team member Philipp Dumitrescu, who was at the Flatiron Institute in New York City when the experiments were carried out. A paper describing the work was published in Nature on July 20. Opening a portal to an extra time dimension—even just a theoretical one—sounds thrilling, but it was not the physicists’ original plan. “We were very much motivated to see what new types of phases could Read More ›
