PsiQuantum has a plan to make a massive quantum computer out of light<\/strong><\/h3>\n

The machine that could change the world will be housed in a room that looks like a data center crossed with an ice cream factory.\u00a0<\/p>\n

Inside, some 100 stainless-steel cabinets each hold hundreds of chips. On those chips, thousands of light particles will fly through a maze of optical switches and beam splitters. Each photon must be accounted for, because precisely measuring where it ends up will help answer questions that current computers might take millions of years to solve.<\/p>\n

This computer, as described, does not exist. It\u2019s the brainchild of a company called PsiQuantum, founded in 2016 by four physicists from UK universities. In a crowded field of deep-pocketed competitors with similarly fantastical visions, the company aims to be the first to build a useful quantum machine.<\/p>\n

MIT Technology Review Narrated: inside the world\u2019s deepest and longest subsea road tunnel<\/strong><\/h3>\n

\u2014Niall Firth<\/em><\/p>\n

I\u2019m currently around 1,000 feet beneath the North Sea, in a dark, dank cave. It smells weird. And I\u2019m increasingly aware of the pressure from millions of tons of seawater just above my head.<\/p>\n

I\u2019m under the iconic fjords of Norway to visit what will soon become the world\u2019s longest and deepest subsea road tunnel\u2014an exceptional engineering feat that will carry drivers deep beneath the North Sea.<\/p>\n

I\u2019m here to understand how you make a 16.6-mile highway that sits 1,280 feet below the sea at its deepest point. And also\u2014at a time when it can feel hard to get anything done\u2014to reassure myself that ambitious engineering is still possible. That we can still make things<\/a>.\u00a0<\/p>\n

Hackers made death threats against this security researcher. Big mistake.<\/strong><\/h4>\n

In April 2024, an anonymous hacker began posting death threats on Telegram and Discord channels aimed at a cybersecurity researcher named Allison Nixon. It wasn\u2019t long before others piled on. Someone shared AI-generated nudes of her.<\/p>\n

They targeted Nixon because she had become a formidable threat. As chief research officer at the cyber investigations firm Unit 221B, named after Sherlock Holmes\u2019s apartment, she had built a career tracking cybercriminals and helping get them arrested.\u00a0<\/p>\n

For years, Nixon had lurked quietly in online chat channels or used pseudonyms to engage with perpetrators and bring them to justice. Now, she resolved to unmask the people behind the death threats\u2014and take them down for crimes they admitted to committing.\u00a0<\/p>\n
