A team of scientists from the California Technological Institute (CALTECH) designed the new method of storing quantum information using sound waves. The results of the study are published in the journal Nature Physics.
Today, quantum calculations are increasingly developing, and special methods are needed to store quantum information. Scientists, led by Mohammad Mirhosseyni, have developed an effective way to convert electrical quantum states into sound and vice versa. This method is based on the use of phonons – sound analogue photon.
The principle of storing information using sound can be represented as an echo in a room that retains sound waves. In reality, the researchers used a miniature device consisting of flexible plates vibrating from sound waves at extremely high frequencies.
“Our method allows you to store quantum information from electrical circuits for a time exceeding similar indicators of other compact mechanical devices by two orders of magnitude,” said Alkhim Bozkurt, a graduate student of the Mirhosseyni group.
The new method is independent of the properties of specific materials, which makes it compatible with existing quantum devices based on microwaves. This opens up new prospects for storing and processing quantum information, which is a key aspect in the development of quantum technologies.
