For a key step, the sound waves for the first time to achieve control and modulation on the chip

In the latest issue of Harvard University, a scientist in the United States wrote in the latest issue of "Nature · Electronics" that they first demonstrated how to use the electric field to control and modulate sound waves on the chip, and the final development of sound -science integrated circuits was one step closer.

Researchers point out that although the electromagnetic waves of the same frequency are slow, there is also its own advantages: short sound waves can be easily limited in the nano -level structure, it is not easy to "talk" with each other, and it is strong with the system that limits it. Interaction, which allows them to be widely used in classic computing systems and quantum computing systems.

The latest research senior author and Harvard University School of Engineering and Applied Science (SeaS) Professor Malco Longca explained: "Sound waves are hoped to become information carrier on quantum and classic information processing chips, but scientists have not been able to take low as low as low. The losses and scalability control the sound waves, which hinders the development of sound wave integrated circuits. In the latest research, we prove that the sound waves can be controlled on the integrated lithium pyromate platform, so that we can be closer to the acoustic integrated circuit. "

Longka and their teams use the unique features of lithium crickets to build a electro -sound modulator on the chip to control the spread of sound waves in the waveguide on the film. Studies have shown that by applying electric fields, the modulator can control the phase, amplitude, and frequency of the sound waves on the chip.

The first author of the paper, former SEAS post -doctoral Shao Linbo said: "This work promotes the progress of the use of sound waves for quantum and classic computing. The previous acoustic equipment was passive, but now we use the electric field to actively adjust the acoustic equipment to be used for the use of can be used for available for the use of for use for the use of sound equipment to be used for available for use for being used for for being available for use for available for it for for being used for available for use for being available for for being used for availability. The next -generation microwave signal processing based on sound wave -based high -performance devices and circuits, as well as paving the road and interfaces connecting different types of quantum system (including solid -state atom systems and superconductant quantum bits). "

Researchers said that although they are currently just showing equipment on a chip, they are trying to build a more complex and large -scale sound wave circuit and interconnect with other quantum systems (such as diamonds). The diamond color refers to the nitrogen-empty color heart in diamonds. It is the most common point defect in the diamond crystal structure and the most representative quantum system at present.
