said that there were certain molecular arrangements that could not be reached from one to the other," said Kenneth Brown, the Michael J. Fitzpatrick Distinguished Professor of Engineering at Duke."That constraint, called a geometric phase, isn't impossible to measure, but nobody has been able to do it. Using a quantum simulator gave us a way to see it in its natural quantum existence.
But due to a mathematical quirk in the system that emerges from the underlying mathematics, called a geometric phase, certain molecular transformations can't happen. The blanket can't wrap entirely around the mountain. In the paper, Whitlow and coworkers used a five-ion quantum computer built by the group of Jungsang Kim, the Schiciano Family Distinguished Professor of Electrical and Computer Engineering at Duke. The quantum computer uses lasers to manipulate charged atoms in a vacuum, providing a high level of control. Whitlow and Zhubing Jia, a Ph.D.
