Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems.

Impressively, the unit registered the lowest frequency loss of any chip to date. Specifically, the engineers noted that the new chip was 15x more stable and 100x more efficient in terms of microwave ...
