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.

South Korea\'s team won gold medals across the board at the 56th International Physics Olympiad held in Bucaramanga, Colombia, the Science Ministry and the Korea Foundation for the Advancement of Science and Creativity said. All five Korean contestants took gold, with one ranking first overall. The national team also won gold at the 39th International Young Physicists\' Tournament in Zurich, its first gold there since 2018, after finishing second overall in the preliminary rounds.
