Acoustic Metamaterial Mimics Quantum Phenomena, Enabling New Tech

Frustration with quantum mechanics' limitations has spurred a breakthrough at EPFL, Switzerland. Researchers, led by PhD student Mathieu Padlewski, have engineered an acoustic metamaterial to explore condensed matter, bypassing the sensitivity issues inherent in quantum systems. Published in Physical Review B (March 2025), this innovation uses sound waves to study densely packed atoms without disturbing their delicate states. This metamaterial, composed of adjustable 'acoustic atoms,' can synthesize phenomena beyond the natural realm, potentially revolutionizing telecommunications by guiding energy waves and enabling energy harvesting from ambient sound. Inspired by the quantum paradox of Schrödinger's cat, the device allows observation of superposed states without collapsing them, unlike direct quantum measurements. Future applications extend to medical fields, mimicking the cochlea to study hearing problems like tinnitus, and the development of acoustic analog computers capable of processing vast amounts of data simultaneously. This interdisciplinary approach merges quantum physics with acoustic engineering, opening new avenues for scientific exploration and technological advancement.
