Research on Quantum ComputersA quantum computer that performs calculations using oscillations
When it comes to storing information, quantum computers have so far run up against technical limitations. Instead of electromagnetic storage, researchers are now using mechanical vibrations. Their vibrating memory can store significantly more information in a smaller space.

The new quantum chip developed by ETH physicist Yiwen Chu contains so-called mechanical resonators—tiny components that begin to oscillate when storing information. The chip is about 7.5 millimeters long, 2.5 millimeters wide, and 1 millimeter high—roughly as wide as a small fingernail. © Hybrid Quantum Systems Group / ETH Zurich
