Sunlight-powered generation of correlated photon pairs

Pairs of correlated or entangled photons are a foundational resource in quantum optics. They are most commonly produced through spontaneous parametric down-conversion (SPDC), a nonlinear optical process that typically relies on a stable, coherent laser to pump a nonlinear

AI radio hosts demonstrate why AI can’t be trusted alone

Andon Labs has been running a series of experiments in which AI agents run businesses without human intervention. Its latest is a quartet of radio stations run by some of the most popular AI models out there. "Thinking Frequencies" is run by Claude, "OpenAIR" by ChatGPT,
