When quantum systems, like those used in quantum computers, operate in the real world, they can lose information to mechanical vibrations. New research led by MSU, however, shows that a better understanding of the coupling between the quantum system and these vibrations can be used to mitigate loss. The research, published in the journal Nature Communications, could help improve the design of quantum computers that companies such as IBM and Google are currently developing.

Researchers led by MSU’s Johannes Pollanen have developed a new device to help future quantum bits, or qubits (pronounced “Q bits”), take flight. Using liquid helium and readily available modern telecommunications technology —based on so-called “surface acoustic wave” devices — the Spartan team has created a new way to precisely manipulate electrons. With this capability, scientists can envision building what are known as trapped-electron quantum computers powered by processors whose quantum bits are free to move — or fly — around. The team showcased its new tech on July 6 in the journal Nature Communications.
