In the HiPEQ project, a consortium of industry and research partners has developed new laser-based approaches to enable miniaturized, robust beam sources for quantum technology. Among others, the ...

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 ...

Metasurfaces are planar, subwavelength‐structured interfaces that impart tailored phase, amplitude or polarisation changes to incident terahertz radiation. By engineering the arrangement and geometry ...

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 ...
