UBC researchers are proposing a solution to a key hurdle in quantum networking: a device that can “translate” microwave to optical signals and vice versa. The technology could serve as a universal translator for quantum computers—enabling them to talk to each other over long distances and converting up to 95 per cent of a signal with virtually no noise. And it all fits on a silicon chip, the same material found in everyday computers.
Every query typed into a large language model (LLM), such as ChatGPT, requires energy and produces CO2 emissions. Emissions, however, depend on the model, the subject matter, and the user. Researchers have now compared 14 models and found that complex answers cause more emissions than simple answers, and that models that provide more accurate answers produce more emissions. Users can, however, to an extent, control the amount of CO2 emissions caused by AI by adjusting their personal use of the technology, the researchers said.
Using population sample survey data, this study shows bike-sharing boosts household consumption by up to 6.8% and dining by 4.9%, as a catalyst for local development. The positive externalities are driven by reduced commuting time, increased leisure, and lower rental costs.
To find the best catalyst for green ammonia, researchers were staring down 8000 lab experiments. With AI, they only needed 28.
