Fingernail-sized quantum chip stores data with vibrations and works like a guitar

A new design for a fingernail-sized quantum chip stores information using tiny mechanical vibrations, researchers said. Applying the principle of vibrating guitar strings, the structure could increase a quantum computer's working memory and points to a path toward next-generation quantum memory. Researchers at ETH Zurich developed a chip architecture that separates quantum computation from information storage. They validated basic performance by running quantum Fourier transform and a period-finding algorithm.
