 Researchers created a new method to manipulate qubits by using sound. 

Theoretically is possible to move even photons by using soundwaves. Soundwaves are molecular movements, and directly pushing photons using air molecules is impossible. But it's possible to use molecules or atomic clouds to push smaller atoms. Then smaller atoms will push smaller and smaller particles. 

If the chain in the series of smaller particles is long enough, the particles will turn smaller and smaller. It's possible. That push to the molecule can send from the series of atoms and subatomic components to photons. In this case particle series whose size decreases during all its series could push photons. 

But manipulating qubits by using soundwaves can happen by stressing piezo-electric crystals with soundwaves. The other version is to point sound waves to photonic crystals. Then the soundwaves can affect the crystal's symmetry. Changes in photonic crystal symmetry affect the movements of quantum elements in those crystals. 


"Acoustic resonators, found in devices like smartphones and Wi-Fi systems, degrade over time with no easy way to monitor this degradation. Researchers from Harvard SEAS and Purdue University have now developed a method using atomic vacancies in silicon carbide to measure the stability of these resonators and even manipulate quantum states, potentially benefiting accelerometers, gyroscopes, clocks, and quantum networking."

The researchers of Harward SEAS (School of Engineering and Applied Science) laboratory used silicon carbide in a test where they manipulated atomic vacancies in the material by using sound waves. As I wrote before soundwave is a pressure impulse. When pressure impact hits the piezoelectric layer it turns to electromagnetic waves. The thing where the piezoelectric layer turns electric impulses back to soundwaves is not very difficult to make. 

The system can send electric impulses from the piezoelectric layer to a loudspeaker that is connected to the amplifier. The piezoelectric layers can connect with transistors that can increase their signal power. This kind of system can allow next-generation security for signals and communication. 

The ability to use soundwaves to control qubits can used to make the next-generation underwater communication. And there are many other applications for this kind of system. The system that can control qubits with soundwaves or qubits that control soundwaves can have applications for nanotechnology and other things. In nanotechnology, the precise controlled soundwaves can push objects, that are smaller than molecules.
