Hybrid diamond chip strengthens interactions between light and quantum bits

Researchers have developed and demonstrated a new hybrid photonic platform that integrates quantum emitters with photonic devices, providing a way to reliably control the interaction between photons and quantum information carriers. The chip-based platform, which combines gallium phosphide (GaP) with a diamond substrate, could help make quantum networks more practical by providing a way to…

Waymo’s robotaxis are headed to Canada

Alphabet’s self-driving car unit, Waymo, is expanding into Canada after receiving approval to participate in Ontario’s automated vehicle pilot program. The company isn’t launching a robotaxi service just yet, though. Waymo tends to follow the same playbook for every new city, gradually proceeding from manual mapping to testing, and eventually operating a commercial service. Waymo…
