A quantum computer might seem to have little in common with a guitar, but researchers at ETH Zurich have found a surprising connection. Physicist Yiwen Chu and her team have developed a system that uses microscopic mechanical vibrations to store and manipulate quantum information, much like the vibrating strings of a guitar produce musical notes.
Unlike the sounds produced by a musical instrument, these vibrations occur at frequencies far beyond human hearing. They take place within a tiny quantum chip, where they serve as a new form of computer memory.
By harnessing these vibrations, the researchers have created a way for quantum computers to process information efficiently while accessing a flexible working memory. "The interaction between the quantum processor and the quantum memory provides a crucial foundation with a view to establishing quantum computers as a powerful and reliable way to perform computations that are not feasible with conventional computers," says Yiwen Chu.
The breakthrough, described in the journal Science, introduces a different approach to quantum computer design. Instead of closely integrating information processing and storage, as many existing systems do, Chu's team has developed an architecture that gives these functions more distinct roles.
