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 ...

Atoms in a crystal form a regular lattice, in which they can move over small distances from their equilibrium positions. Such phonon excitations are represented by quantum states. A superposition of ...

Device could help link different quantum systems, supporting advances in computing and secure communication. (Nanowerk News) Researchers have created a chip-based device that can split phonons — tiny ...
