Scientists achieve quantum communication across 250 km of conventional fibre optics.

A study published in Nature marks a major step in quantum computing, demonstrating the coherent transmission of quantum data across 250 kilometres of standard fibre-optic cable between Frankfurt and Kehl in Germany — without the need for cryogenic cooling.

"When asked directly about the most pressing digital threats, be it AI misuse or quantum computing, Schneier quipped. "I generally hate ranking threats, but if I had to pick candidates for 'biggest,' it would be one of these: income inequality, late-stage capitalism, or climate change," he wrote. "Compared to those, cybersecurity is a rounding error."

Asked directly about NSA reforms post-Snowden, Schneier was skeptical, responding: "Well, they haven't had any leaks of any magnitude since then, so hopefully they did learn something about OPSEC. But near as we can tell, nothing substantive has been reformed."

Schneier further clarified, "We should assume that the NSA has developed far more extensive surveillance technology since then," stressing the importance of vigilance.

He touched on the fusion of AI and democracy - a theme of his upcoming book Rewiring Democracy - noting that he didn't "think that AI as a technology will change how different types of government will operate. It's more that different types of governments will shape AI."

He is pessimistic that countries will harness AI's power to do good and help improving quality of life.

"It would be fantastic if governments prioritized these things," he said. "[This] seems unrealistic in a world where countries are imagining some sort of AI 'arms race' and where monopolistic corporations are controlling the technologies. To me, that speaks to the solutions: international cooperation and breaking the tech monopolies. And, yes, those are two things that are not going to happen.""

Great call to action by Robbie King on finding more useful quantum algorithms.

Billions of euros have been spent on research for advancing the development of quantum computers, but what are they useful for?

As the post-quantum transition progresses, the main incentive for quantum computers is going away.

Robbie claims "The bar for meaningful progress is lower than it might seem, and even incremental advances are valuable.”
