You can’t divide the indivisible, unless you use quantum mechanics. Physicists have now turned to quantum effects to split phonons, the smallest bits of sound, researchers report in the June 9 Science ...

Researchers developed a chip-based single-phonon directional coupler that carries out controllable splitting and achieves quantum-level performance. The device could enable microscopic on-chip routers ...
