The quantum realm creates multiple challenges for quantum systems, such as scalability, the unintentional interaction of signals, and the limited lifetime of fragile quantum information. Vibration, heat, material defects, and electromagnetic noise also have a great impact at the quantum scale.

Acoustic waves offer a compact and sustainable way to process and route signals, opening new possibilities for quantum and microwave technologies, according to the study.

“In nature, an atom has distinct energy levels that electrons can jump between,” said Shao. “Our acoustic atom is a device with distinct energy levels for acoustic waves. Using electrical fields, we can drive transitions between these acoustic energy levels, mimicking real atoms.”
