Using mechanical vibrations instead of magnetic memory for quantum computing

Using mechanical vibrations instead of magnetic memory for quantum computing

Quantum computers still face limits when it comes to storing information. Researchers at ETH Zurich are now turning to mechanical vibrations rather than electromagnetic memory. Their new vibrating memory can store significantly more information in a smaller volume. Combined with a suitable computer architecture, it also enables the efficient solution of complex computational problems.
