Data learned to encrypt and send using sound

Traditional computer chips run on electricity, while newer photonic chips useNow. 

Scientists from Harvard have presented a new type of chip that transmits data in the form of sound waves.

An acoustic chip works similarly to a photonic chip, but with sound waves instead of light waves. The team created a modulatorfrom lithium niobate, which changes the elasticity in response to the electric field and producesacoustic waves. By carefully adjusting it, the modulator can control the phase, amplitude and frequency of acoustic waves, encoding data in them before sending them through the waveguides. 

The authors of the development note that chips withAcoustic waves have potential advantages over conventional electromagnetic waves. They are easily confined to tiny waveguide structures, do not interfere with each other, and interact strongly with other parts of the system in which they are used.

Now scientists are looking for a way to connect acoustic chips to quantum computer components, such as superconducting qubits. The study was published in the journal Nature Electronics.
