 In this paper, quantum mechanical adiabatic passage was used to design spatial acoustic four-wave guide, WG, couplers. The behavior of propagating waves in these couplers is similar to quantum states driven by external fields, allowing for the mapping of quantum states to classical waveforms. These couplers could have potential applications in acoustic communication, filtering, and detection. This article was authored by Shui Tang, Jin Lei Wu, Cheng Lu, and others.
