PsiQuantum, founded in 2016 by four UK physicists, plans to build a massive quantum computer using light particles. The machine would house 100 stainless-steel cabinets holding hundreds of chips where thousands of photons navigate optical switches. Precisely measuring each photon's path could solve problems current computers need millions of years to crack.

Meanwhile, 1,000 feet beneath the North Sea, engineers are constructing the world's longest and deepest subsea road tunnel. The 16.6-mile highway will sit 1,280 feet below sea level at its deepest point, cutting through Norway's iconic fjords. This exceptional engineering feat demonstrates ambitious infrastructure remains possible.

Today's must-reads include Meta allegedly using AI to target workers with health issues for layoffs, OpenAI's first consumer device—a screenless AI companion speaker—and the US military deploying explosive drone boats in combat. DeepMind's CEO Demis Hassabis calls for a US-led body to test frontier AI models, while data centers face billions in new power costs across 13 states.

In cybersecurity, Allison Nixon, chief research officer at Unit 221B, faced death threats and AI-generated nudes after tracking cybercriminals. She resolved to unmask her harassers, turning the tables on those who admitted crimes in online channels.
