When I temporarily switched from an iPhone to an Android phone last week, I was bracing for a world of hurt. I’ve owned only Apple phones ever since buying the first-generation iPhone in 2007. And,…
Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a circular grating (center dot…
A high-level schematic of the photonic integrated chip, developed by the Gaeta lab, for all-optical optical frequency division, or OFD – a method of converting a high-frequency signal to a lower frequency. Credit: Yun Zhao/Columbia…
With WWDC 2024 now set, Apple continues to work on bringing itself more in line with US government demands. What we don’t know yet is the extent to which these changes will be restricted to…
Synergistic effect of thermal activation and plasma. Credit: POSTECH Imaging being able to wear your smartphone on your wrist, not as a watch, but literally as a flexible band that surrounds around your arm. How…
Scale AI, the data processing company that advertises itself as a way to train generative AI on higher-quality information, has apparently shut down access to its platform in several countries, leaving gig workers in the…
A quantum emitter centrally placed within a hybrid metal-dielectric bullseye antenna, designed for highly directional photon emission. The antenna’s unique structure allows photons to be efficiently coupled directly into an optical fiber, showcasing a pivotal…
In a sign that the tech industry keeps getting weirder, Meta soon plans to release a big update that transforms the Ray-Ban Meta, its camera glasses that shoot videos, into a gadget seen only in…
Microsoft’s Copilot AI could soon run locally on PCs rather than relying on the cloud. Intel told Tom’s Hardware that the chatbot could run on future AI-enabled PCs that would need to incorporate neural processing…
