Device for translating quantum states into sound waves

2023: Product Announcement

On June 22, 2023, American scientists from the California Institute of Technology announced the development of a new technology for storing information in quantum computers. We are talking about the translation of electric quantum states into sound waves.

Quantum computing systems, like traditional computers, require the means to store the data they operate on. However, an optimal solution to the problem has not been found. The new method involves the use of phonons - quasiparticles, which are the sound equivalent of photons. It is noted that the choice of scientists fell on phonons because with their use it is theoretically possible to design a relatively compact and productive device for recording and extracting information in quantum systems.

New technology for storing information in quantum computers has been developed

To illustrate the principle of operation of an instrument for storing quantum information in sound waves, the researchers give the following example. Imagine a room with a strong echo. Now let's say you need to keep your grocery list for evening shopping - you open the door to that room and shout "Eggs, bacon and milk!," then close the door. An hour later, when it's time to go to the grocery store, you open the door, shove your head inside and hear your own voice, still echoing: "Eggs, bacon and milk!"

The research team's solution is a tiny device made up of flexible plates that vibrate under the influence of extremely high frequency sound waves. When these plates receive an electric charge, they are able to interact with electrical signals carrying quantum information. This allows you to transfer information to the storage device, and later extract it if necessary.^[1]
